General Options: Desktop Performance Tab
The General > Desktop Performance options allow you to change settings for animation, pre/postprocessing, disk space warnings, and updating reports.
Report Update Options for Design Type:
- Select a Design type to which the report update options apply.
- Select or clear Dynamically update reports and field overlays during edits.
If selected, report plots and overlays update dynamically.
- Update reports on file open – specifies that reports be automatically updated whenever an existing file with solution data is opened for viewing/editing. Enabled by default.
- Dynamically update postprocessing data for new solutions.
Updating numerous reports may take a significant amount of time. Updating reports during the analysis process can impact the overall time to solution. You may want to vary the times when your reports get updated relative to the impact on overall solve time.
Five options exist for updating reports during solutions:
- Automatically – the default setting that updates most things immediately. For the AdaptivePass plot context, plots are updated at the end of each solution pass. For LastAdaptive, or Transient, the plot is updated at the end of the transient or adaptive solution. This option balances report and field plot updating with solution time. For example, reports may be updated after each adaptive pass but field plots will not be updated until the solution is complete.
- Immediately – update reports and plots as soon as data comes from the solver. This option will have the greatest impact on the overall solution time, but will have the most rapid updating of reports and field plots. Caution should be used in selecting this option. Some types of reports and field plots may take a long time to update, especially as the mesh size increases.
- Never - only manual intervention updates reports. This option will prevent updates from impacting the solution time.
- On Completion - a single update is done when the solve completes.
- After Each Variation - when performing an Optimetric or parametric analysis, all reports are updated after analysis of each variation has been completed.
Animation
Computing animated plots requires significant memory that 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.
The Animation setting lets you set a limit to Stop computing animation frames when available memory is less than the set value in megabytes. The default is 100.
Desktop Pre/Post Processing Settings:
-
Number of Processors – The default is determined by the number of logical processors on the machine. This option is common for both preprocessing and postprocessing. This option only affects pre/post processing in Desktop (not solve or simulation).
More details regarding the default core usage:
- The default core usage per desktop session (UI + solve) is set to 2/3 of the logical processors on the machine.
- The cores for default local config is max{4, 1/3 of the logical processors on the machine}
- The default number of processors for pre/post is min{1, 2/3 of the logical processors - default_cores_for_local_config}
- When the core usage per Desktop session cannot be evenly distributed between solve and pre/post, more cores will be assigned to solve.
Example 1:
- logical processors = 24
- cores usage per desktop session = 16
- local HPC set to 4 cores
- processors for pre/post set to 12
Example 2:
- logical processors = 20
- cores usage per desktop session = 13
- local HPC set to 4 cores
- processors for pre/post set to 9
Example 3:
- logical processors = 5
- cores usage per desktop session = 3
- local HPC set to 2
- processors for pre/post set to 1
The following preprocessing algorithms can take advantage of multiple processors:
-
Visualization/faceting of 3D models for 3D products
-
Model validation for 3D products
-
Auto net identification for Q3D only
Disk Space Warning
You can set a value to Warn when available disk space is less than the specified number of gigabytes.
When all information on the Desktop Performance panel is defined, select another option under General in the Options dialog or click OK to put your settings into effect.
