Explorer

The Explorer window is very useful for carrying out a number of tasks:

1. To toggle between flowsheets and trend windows within a project.
2. To search for models in a project, as it contains a list of all models in a project sorted by Class (model type).
3. It contains a search facility to enable users to search for a specific tag, similar to the Find Tag command.
4. Users may copy a list of the units in the project, or in a flowsheet, to another application. They may copy all units or selected types of units, such as Pipes which makes it useful when setting up Excel reports.
5. To Activate or De-activate flowsheets.

Please see Explorer Window for more details on the above functionality.

Project

Command Path View, Project

Please see the Project Window section for details on this dialogue box.

Message

Command Path View, Messages

This will open the Message Window.

Quick View

Command Path View, Quick View

The Quick View list is used to quickly access some unit model information from the Graphics Window. Each unit type has its own Quick View list. Some models may have default lists configured already. However, the user can customise these lists as described below. When the Quick View command is activated, it opens the Tag Lists dialog box.

To build a customised Quick View list, open the Access Window for the unit of interest. Select the variable(s) you want to add to the Quick View list using the left mouse button, then right click on the variable, choose Send to Quick View (F6). The selected variables will be added to the tag list window. While the Tag lists dialog box is opened, you may continue to add variables to the list. Keeping in mind that the model type selected matches the model opened (Access Window). When a variable has been added to the Quick View list, a small blue dot will appear to the left of the variable name in the Access Window.

Please NOTE that you may specify the maximum number of the quick view entries (global option, same for all unit operation types) by entering a value in the Max Value Length box. The default is 20.

Once variables are added to the Tag lists window, you may modify it in a number of ways. Left click on the variable's label name to select it, once selected, you may:

• Move it up or down the list to position the variables in the right order using the Move Up and Move Down buttons.
• Remove the variable from the list using the Remove button.
• Right click on the label to change the conversion units and formats of the number.
• Left click on the label to rename it.

When finished, close the Quick View List to save it.

When a Quick View list is configured, the user may view it from the graphics window. See Left Mouse Click On Graphics Symbol.

If the Save in Cfg option is checked, the Quick View information will be saved to a file called SCD_RTL.ini in the project group\cfgfiles folder. This way, the Quick View configurations can be shared between projects.

Controls

Command Path View, Controls

Right clicking on the Graphics Window background can also access this.

THIS PAGE IS USED TO AUTO-TUNE CONTROLLERS IN THE PROJECT, WHILE THIS STILL WORKS, IT IS BEING SUPERSEDED BY Trend Window (with PID Controllers).

This opens the $Ctrl Access Window. This access window can be used to Auto-Tune controllers in the project. To do so, the user must first tick the option in the Tuning Tab page.

The Controls Tab page lists all the controllers used in the project. Only one Controller may be tuned at any one time. The controller in view is selected from the list on the bottom half of the page. In the example shown below, the Plant.WaterMakeup controller is selected (marked by a tick in the V [View] column). To Auto-Tune this controller, the user should then tick the box under the T [Tune] column. When the controller is under the Auto-Tune mode, SysCAD holds all other controllers steady and performs the tuning routine. When the controller is tuned, it overwrites the user specified Gain and Proportional Band values with the optimum values derived from the tuning exercise.

The user may then repeat the exercise to tune other controllers in the project.

Note: As with any real life operating plants, some controllers may need more fine tuning depending on the interaction with other controllers. In most cases, it is best to hand tune some of the more sensitive controllers first to get the plant under control and use the auto tune for optimisation.

Power Supplies

Command Path View, Power Supplies

Right clicking on the Graphics Window background can also access this.

This is used to turn the supplied power on/off, mainly used in conjunction with electrical group of models. NOTE: user should leave these power options switched on as some unit operations do require the power to be connected to function.

User can add in new types of power supply by change the number field and filling in the information when the new fields are created. Alternatively, the existing source can be edited.

Once the power supply is created on this page, it is available for selection in some unit operations. Examples of such are valves, pumps, crushers and so on.

To be completed.

Plant Area

This is a project wide Area Model. All individual area models belong to the Plant Area. The Plant Area is the default Area to which new units and links belong.

Species Data

Command Path View, Species Data

Right clicking on the Graphics Window background can also access this.

This opens the $SDB Access Window. An example of the species property access window is as follows:

The above display of the species properties is the SysCAD interpretation of the data loaded for the project. This serves both as a check for the property data and useful data for the SysCAD users while solving the project.

The above Species Property Data is given for temperature 0°C and Pressure 101.31 kPa. These temperature and pressure can be changed to obtain species properties at different conditions. Users can choose to display the data in either mass or mole basis. This is done via the Mass Basis check box, it toggles between the two options.

Users can also choose to use the Hi or Low Fidelity (accuracy) steam/water model to predict the properties. This is done via the HiFidelity check box.

Right clicking on any property value in the above data table will bring up a pop up menu with the following options:

• Conversion: The engineering units for the column can be changed where applicable.

• Format: The format for the column can be changed.

• Copy Full Tag: When the data is presented as a matrix, the conventional Copy and Paste method would not copy the tag properly. To copy the full tag for use in the trend window or other referenced files such as excel or pgm, use this copy full tag command. The format is:

$SDB.compound(phase).ColumnHeading(@ Temp & Pressure) (units)

To paste the tag, use <Ctrl + V> as normal.

• Copy Value/Copy: When the data is presented as a matrix, the conventional Copy and Paste method would not copy the tag properly. To copy the tag value for use in the referenced files such as excel or pgm, use this copy value command.

• Paste: As the variables are all calculated or for display only. Values cannot be pasted onto the table.

Tolerances

Command Path View, Tolerances

Right clicking on the Graphics Window background can also access this.

The $Tol Access Window lists all tolerance values used in various solve routines. These include both System routines and model-based routines. An example is shown below. The user can change values in this window to help speed up convergence. See Tolerance Testing for an explanation of how SysCAD uses these tolerances.

Tear Blocks

Command Path View, Tear Blocks

Right clicking on the Graphics Window background can also access this.

Related Topics: Convergence Methods, Tolerance Testing.

The $Tears Access Window lists all the tear blocks information for the project. It may contain a number of pages depending of the project. If there is no tear block present in the active project, only the Tears tab page will be displayed. If Tear blocks are present in the project, then all tear blocks will be listed as shown in the example below.

Convergence Defaults / Tolerance Defaults: This is the global solver method selected for the project; this is being set in Project - ProBal Setup. Some damping factors can be set for selected methods, for more information on the factors and methods, please refer to Damping Factors for a glimpse of the C++ code used. Please note that the user need not change any of this information for the project to solve. However, for the keen and experienced modeller, some factors and tolerances can be adjusted to speed up the solve routines.

Tear Tag: This is the name of the tear block.

Method: The method for individual tear blocks can be changed. Options are: Direct Substitution, Adaptive Direct Substitution and Wegstein Acceleration.

Damping Rqd: The damping factor for the tear block if it is damped as a group. Symbol * mean the factor will be determined and changed by SysCAD, whereas a number will hard wire the damping factor to a set value.

Grp: This means all variables in the tear block will be damped as a group or individually.

Tolerance Strategy: Options are: Priority, Maximum or Minimum.

Abs / Rel: Each tear block can have its own tolerance factors.

Viewing icon: To the left hand side of the Tear Tag, there is a column of magnifying glass icons. This is the active tear block selection button. When a tear block is selected, detailed tear block variables information will be displayed in the Damping and Tolerance Tab page. From these pages, the user is allowed to change damping/tolerance factors to the individual variables if required.

Find Graphics icon: The two columns of binoculars will find the Unit operation and the tear stream respectively for the tear block on the graphics window.

Change Stats

Command Path View, Change Stats

Right clicking on the Graphics Window background can also access this.

This access window displays statistical information on change of values during Solve or Run. To start collecting the information, the collect tick box must be selected and solve/run started.

In the Errs tab page, the largest error encountered will be listed, while the chngs and Osc tab pages will list variables that have the most changes and the worst oscillations respectively.

As with all access windows, the changes will not update unless the refresh button is pressed. Also, the collection of the statistical data will add to the memory usage; if the project is big, the user can experience a much slower solve speed. Therefore, only use this feature if debugging is required. Once debugging is done, un-tick the collect option to switch off this feature.

Evaluation Order

Command Path View, Evaluation Order

Right clicking on the Graphics Window background can also access this.

This will open the order Evaluation Window. This window contains fairly useful information, eg, it shows how the solver network is built, the relationship between the units, the tears streams, the project input and output units and some PID controllers information.

As this window displays how the project is solved information will only be gathered when the solver has been activated. If you have opened this window before solve, press the Refresh button to update the display.

To illustrate how to use this window, an example of a very simple project (Tutorial project DigestF3.spf) and its Order of Evaluation Windows are shown below. Note that as the complexity of the project grows, so does the relationship between units, which can become very large.

The options for the evaluation order window are:

The number of columns displayed depend on the options selected above, they may include:

1. Seq - Sequence number
2. Inputs - This is the input stream to the node / unit operation.
3. Node - The unit operation
4. Outputs - This is the output streams from the node / unit operation.
5. Mv - This is the measured value, only applies to the control values. NOTE: these will be in SI units.
6. Qm, T, P, (Solids fraction), (Liquid fraction) or dQm, dT, dP etc columns will appear based on selection of IO list box.

A number of features to look out for are:

1. If the Process option is selected, it will display all the process flow dependencies, including the control information.
2. If Option Control is selected, it will display all the General Controllers and PID controllers showing their dependent streams.
3. Units are grouped into little networks to indicate their dependency. Each group is shown in the order the units are evaluated. .
4. The plant model input and output streams are indicated by .
5. The tear streams are indicated by .
6. Control streams are indicated by .
