This page can be used to help with debugging the project when required. User can switch on / off various options to help narrow down the problem area.

Tag (Long/Short) Input/Calc Description
Analysis...
Requirements
Trace.On Tickbox By default, the Trace.On is always switched off when a project is loaded (the setting is intentionally not saved). When the user requires this feature, simply turn it on, then run the project to see the largest change in the project.
History.Length Valid Range 3-20 This effects how many columns are being displayed or reported per variable. For example, if Show.Values are on, and History.Length = 5, then these columns Val[0] - Val[4] will be shown in the Results section.
Collect..
AllChanges Tickbox Collect all the changes (this will contain a lot of information)
Temperature Tickbox Collect temperature values
Pressure Tickbox Collect pressure values
Mass Tickbox Collect Mass values
PhaseFractions Tickbox Collect Phase fraction values
SolidSpecies Tickbox Collect solid species values
LiquidSpecies Tickbox Collect Liquid species values
VapourSpecies Tickbox Collect vapour species values
XRefs Tickbox Collect controller cross reference data

Results Display Options (for customising what is being displayed on screen in the access window, bottom half of the page)

Display...
Select.By Travel Sum of total changes
Travel-In-Step Sum of total changes in the step
Travel-Above Sum of total changes above a user specified value
Travel-In-Step-Above Sum of total changes in the step above a user specified value
Select.Above Input Only visible if Select.By=Travel-Above or Travel-In-Step-Above. User can define a minimum value as collection.
Sort.By None No sorting.
Tag-Sequence Sort by Tag Then by Sequence (Seq Column) in ascending order.
Sequence-Tag Sort by Sequence Then by Tag in ascending order.
Value-Descend Sort by value in Descending order.
Change-Descend Sort by change in Descending order.
Travel-Descend Sort by sum of change in Descending order.
NrmTravel-Descend Sort by change (as a % of range) in Descending order.
NrmTravelRel-Descend Sort by change (as a % of maximum range) in Descending order.
Count Input Number of rows shown in the Display Value Section.
The following Display Tags have these selection options:
  1. Off : Value will not be displayed.
  2. Fixed : Value will be shown in a "narrow" field with 2 decimal points. (user may change the individual values to a different format)
  3. Float : Value will be shown in a "narrow" field in scientific format . (user may change the individual values to a different format)
  4. Fixed-Wide : Value will be shown in a "wide" field with 2 decimal points. (user may change the individual values to a different format)
  5. Float-Wide : Vakue will be shown in a "wide" field in scientific format . (user may change the individual values to a different format)

For more information on the definition of the following terms, see Additional Information

Values Display selection Current value (SI units)
Change Display selection Change of value in the current iteration (SI units)
ChangeNrm Display selection Change of value in the current iteration as a percentage of Change Range.
Range Display selection Range of values in SI units during the current run (since last clear)
Travel Display selection Sum of all absolute changes so far.
TravelNrm Display selection Sum of all absolute changes so far, shown as percent of change range (current variable).
TravelNrmRel Display selection Sum of all absolute changes so far, shown as percent of Max change range (all variables).
Display Values Section: The number of columns and rows will depend on the selections on this page.

  • Value (Val) : Current value in SI units
  • Change (Chg): Change of the value during the last iteration
  • Range : Range of value in SI units during the current run
  • Travel : Total of all movements in an absolute sense eg (0.3 + 0.4 +(-.2) + 0.6 = 1.5
Trace Control (these options are used to minimise change in the project)
AllDiscrete Tickbox Hold all Discrete changes
AllCtrlStrategy Tickbox Hold all control strategy
AllCtrlActions Tickbox Hold all control actions
Tears Tickbox Hold all Tear stream calculations
Solver Control
Run-Then Continue After solve has started, run the number of steps in Step.Count, then continue.
Pause After solve has started, run the number of steps in Step.Count, then pause.
Stop After solve has started, run the number of steps in Step.Count, then stop.
Step.Count Input User specifies how many steps the solver should complete for the analysis. Works in combination with the Run-Then selection.
Clear Button Clears the current data.
Run Button Runs the solution for a number of steps. The number of step is specified in the step.count field.
Idle Button Pauses the simulation.
Step Button Runs the simulation for one step.
Stop Button Stops the simulation.
