How can I restart a Transient Thermal Analysis?

Hello everyone,

I’m working on a script to automatically generate a restart analysis for a transient thermal analysis once the calculation is completed. Ideally, I would like to create a restart object within the existing tree structure rather than generating a new system. However, insights on both approaches would be helpful.

I came across this discussion that provided some useful information, but it seems like it is not applicable to transient thermal analysis:

Does anyone have experience with this or any suggestions?

Best regards,
Olia

Use a python code object for after solve or after post callback. Then use this code to create a restart analysis

Analysis = Model.Analyses[0]  #Your analysis here
Settings = Analysis.AnalysisSettings
Settings.RetainFilesAfterFullSolve=RestartRetainFilesType.Yes
Ext = ExtAPI.ExtensionManager.GetExtensionByName("RestartAnalysis")
ExtMod = Ext.GetModule()
ExtMod.createRestartAnalysis(Analysis)

Woops, just realize you want a thermal analysis restart. That is not supported natively with Mechanical or the restart Add On. You would need to do that through command snippets.

Thank you, Mike! I successfully managed the restart by using the AddCommandSnippet() method to insert a command snippet.
