General Options: Desktop Performance Options

These options are set in the Desktop Performance panel under General in the Options dialog box.

Report Update Options for Design Type

• Design Type – select the design type for which you are setting report update options.
• Update reports on file open– specifies that reports are updated whenever you open a file with solution data. Enabled by default for Twin Builder.

• Dynamically update reports during edits – controls the version of solution data to be reported for the specified Design Type.
  Note:

  Twin Builder solution data is versioned. For example, if you analyze and produce solution data for a particular state of a design — then edit the design and re-simulate — solution data is now available for both states of the design.

To illustrate the effect of the Dynamically update postprocessing data during edits option, consider the following scenario:

• Simulate a design and create a report.

The report displays the current solution data (State 1).

• Make changes to the design.

The report you created is marked ‘Invalid’ (a large “X” appears in the upper-right corner of the report window and on the report icon in the Results section of the Project tree).

• Re-run the simulation.

The report is updated with new solution data (State 2), and the report is marked as valid (the “X” disappears).

• If you click Undo:

Twin Builder still has the previous solution data (State 1). If you disable Dynamically update postprocessing data during edits, the State 2 report data becomes invalid again. If Dynamically update postprocessing data during edits is enabled, Twin Builder reloads the now valid State 1 solution data into the report and marks it valid.

• If you then click Redo:

The result again depends on the setting of the Dynamically update postprocessing data during edits option. If the option is disabled, the report becomes valid again (the State 1 data was not reloaded by the Undo operation, so the report is still displaying State 2). If the option is enabled, the State 2 data is reloaded dynamically and report is also valid.

Animation

Computing animated plots requires significant memory which depends upon the complexity of the plot type. The Animation setting is used to prevent problems related to low memory should an animation require large memory allocation.

Use the entry field to specify the amount of memory in megabytes to preserve when computing animation frames. Animation frame computation stops when the memory limit is reached.

Desktop Pre/Post Processing

Define the number of processors to be used. This setting applies only to pre/post processing algorithms executed on the desktop. Pre/post processing algorithms executed on the engine use the same number of processors as specified for simulation.

Disk Space Warning

You can also have Twin Builder Warn when available disk space is less than the specified number of gigabytes.
