This page is for SysCAD 9.3 Build 137 only. For earlier builds, please see Size Configuration 9.3
Edit Configuration Step 2 of 2 - Size Data Configuration Tabs
There are three tabs for size data configuration:
These tabs will only be visible if:
- You have the Size Distribution add on; and
- You have selected the size distribution dll or group in the Model selection (see Model Selection)
To add a new size distribution, the work flow is as follows:
- On the Size Distribution tab:
- Press the "Add Distribution" button (if not renaming the default "Std" distribution).
- Rename the Distribution and set the relevant parameters (Bottom size, Interpolation Method, Species).
- On the Sieve Series tab:
- Select the new Distribution from the list.
- Define the sizes for the new size distribution using one of the predefined methods or manually.
- On the Measurements tab:
- Select the new Distribution from the list.
- Define the desired measurements for the new size distribution.
|Distribution||Each Size Distribution has it's own sieve series. If more than one Size Distribution is available, click on this list box to choose the correct size distribution for sieve series definition.|
|Units:||You may change the default engineering units for the sieve series by using the Units list box.|
|Manual||Allows the user to manually enter size intervals.|
|Q||Creates a series from the minimum and encompassing the maximum values based where the ratio between series is based on the following formulae:
|Sqrt(2)||Each interval is √2 times previous interval.|
|Ratio||Each interval is Ratio times previous interval.|
|Arithmetic||Linear intervals separated by 'A'.|
|Tyler Mesh||The full Tyler Mesh series. The user may truncate the series by adjusting the minimum and maximum values.|
|US Mesh||The full US Mesh series. The user may truncate the series by adjusting the minimum and maximum values.|
|To Manual||By clicking on this button the user transfers the series data to Manual and changes the specification type to Manual.
|Minimum||the minimum value for the Sieve Series. NOTE: This is the upper value of the smallest size interval. The absolute smallest size possible (lower value of the smallest size interval) is "Bottom Size" defined on the Size Distribution tab page. The Bottom Size must be less than the Minimum value for the distribution. If the Minimum is set to a value equal to or lower than the Bottom Size, then the Bottom Size will be adjusted to half of the Minimum.|
|Maximum||the maximum value used when determining the Sieve Series. Depending on the method, this may not be the upper value of the largest size interval.|
|Number of Points||Displays number of Intervals.|
|Decimals||For non manual types you can specify 0,1,or 2 decimal places.|
|Copy to Clipboard||- This button copies the current sieve series onto the Windows clipboard, allowing it to be pasted into external programs such as Excel.|
|Paste from Clipboard||- This button is only available if Manual is selected. It allows the user to copy a sieve series from an external program such as Excel and paste it into the sieve series box.|
- For the smallest size interval the upper value is the smallest value in the sieve series and the lower value is not zero, it is defined by the user as "Bottom Size" on the Size Distribution tab page.
- When using size separation units, such as Screens and Cyclones the calculated efficiency curve is dependent on the user defined sieve series. Because efficiency curves are usually steep, it is recommended that the user defines as many size fractions around the cut-sizes of interest as possible.
- If the user wishes to use more than one sieve series in a project, then it is recommended that all of the sieve series have the same number of size intervals. This makes reporting and setting values simpler.
- Ctrl+C and Ctrl+V will not work in the sieve series box, use the Copy to Clipboard and Paste from Clipboard buttons instead.
Each Size Distribution has it's own sieve series. If a new size distribution is added, the Sieve Series Tab should be used to configure the size data.
|Distributions||Name||If more than one Size Distribution is available, click on this list box to choose the correct size distribution for Distribution Specification.|
|Add Distribution Button||Adds a new distribution with a default name.
|Remove Distribution Button||Removes a distribution from the list.|
|Selected Distribution Specification||Units||This value is displayed only, you may not change it here. It was defined when the Sieve Series was set up previously.|
|Top Size||This value is displayed only, you may not change it here. It was defined when the Sieve Series was set up previously.|
|Bottom Size||You may define the bottom size for the size distribution, which is used as the lower value for the smallest size interval. This bottom size will be used in some model calculations, in particular it used in calculating the geometric mean of the smallest size interval. NOTE: the bottom size must be less than the Minimum value specified on the Sieve Series tab for the distribution. If the Minimum is set to a value equal to or lower than the Bottom Size, then the Bottom Size will be adjusted to half of the Minimum.|
|Interpolation Method||Linear||Linear interpolation is used when performing size distribution calculations.|
|TSpline||TSpline interpolation is used when performing size distribution calculations. A spline is a special function defined piecewise by polynomials.|
|LogLog||Linear interpolation of the natural logarithm of the size distribution values is used when performing size distribution calculations.|
|LogLogTSpline||TSpline interpolation of the natural logarithm of the size distribution values is used when performing size distribution calculations.|
|Select Solid Species||Species||Selects one or more solid species to contain size data.
This page allows the user to specify which measurements they wish to be calculated for each stream species that has a size distribution associated with it. These measurements appear on the MSz tab page when viewing the Access pages.
|Distribution||This will have a list of the distributions that have been defined in the project. Select the Distribution for which you wish to define measurements.|
|Measurement List||Add Button||Add a new measurement.|
|Remove Button||Remove an existing measurement.|
|Measurements List||The List of defined measurements. The order in which the measurements appear here is the order that the measurements are displayed in the MSz page.|
||Name||The user types in the required measurement name, for example:
|Type||SizePassFrac||Size at specified cumulative passing fraction|
|FracPassSize||Cumulative passing fraction at specified size|
|FracRetainSize||Cumulative retained fraction at specified size|
|MassPassSize||Cumulative passing mass at specified size|
|MassRetainSize||Cumulative retained mass at specified size|
|PPG||Total Particle Count per Mass of solids, please see Size Measurements Data Sections (MSz Tab) for more information.|
|SAM||Surface Area per Gram, please see Size Measurements Data Sections (MSz Tab) for more information.|
|SAL||Surface Area per Litre of liquids, please see Size Measurements Data Sections (MSz Tab) for more information.|
|APD||Only available in SysCAD 9.3. Average particle diameter based on Fraction Passing and Geometric mean size of each size interval|
|Spread||Only available in SysCAD 9.3. Difference in sizes at two specified cumulative passing fractions.|
|MassRangeSize||Only available in SysCAD 9.3 Build 136.19110 and later. Mass flow between two different size ranges.|
|FracRangeSize||Only available in SysCAD 9.3 Build 136.19110 and later. Mass Fraction between two different size ranges.|
|Text||This is a Text Label that will appear on the MSz page|
|Value:||Size or Fraction||calculate the fraction or size at (SizePassFrac and FracPassSize only)|
|Conversion Unit selection||allows user to specify units from a drop down list.|
|Display Order:||Up Button||Move the display order of the selected measurement up the list.|
|Down Button||Move the display order of the selected measurement down the list.|
|Count Factor||This is a correction factor which may be used to account for particle geometry. This value is used when calculating:
|To Calculate||Name||Type||Value||(Value) engineering units||Result's engineering units|
|Particle size at 50% passing||P50||SizePassFrac||50||%||um|
|Cumulative fraction passing 100 µm||m100||FracPassSize||100||um||%|
- If the size specified is between two size intervals, then interpolation (usually on cumulative distribution data) is used to calculate the size or cumulative fraction passing of interest. The Interpolation Method used is specified by the user.
- The PPG number will ignore the count factor.
