Using ACT, how can I create a result for each time step and export result to a text file?

One can adapt the following code:

• Store link to solution

    solu=ExtAPI.DataModel.Project.Model.Analyses[0].Solution
  

• Obtain list of time sets

   ResData=ExtAPI.DataModel.Project.Model.Analyses[0].GetResultsData()
   DataSets=ResData.ListTimeFreq
  

• Loop through data sets

   for DataSet in range(len(DataSets)):
  

• Define display time

        DisplayTime=DataSets[DataSet]
        UnitTime='[sec]'
  

• Insert result and evaluate

        result=solu.AddMaximumPrincipalStress()
        result.DisplayTime=Quantity(str(DisplayTime) + UnitTime)
        solu.EvaluateAllResults()
  

• Export result to text file

       FilePath=r"D:\Test\Export"
       FileExtension=r".txt"   
       result.ExportToTextFile(True,FilePath+str(DisplayTime)+FileExtension)

Hello Pernelle,
thank you for that very useful code. I use it in Mechanical to get the Equivalent Stress results for each time step. But as I have 30 substeps the solution tree is getting quite crowded. Hence my question: is it possible to write the results only into text files without displaying them in Mechanical as Solutions?

Hi @Niklas_01, there are a couple of options here:

• Insert only result in the Mechanical tree and change its display time and export for all time steps. This will however take much longer to execute than the above method.
• Keep the above method and delete all the result objects after you have exported all the info.
• Directly read the result file through GetResultsData
• Use DPF to do the postprocessing.

An example of methods #2 and #3 is given here: https://discuss.ansys.com/discussion/660/how-to-iterate-through-load-steps-for-result-objects
For method #4, see this post on how to get started: https://discuss.ansys.com/discussion/3074/getting-started-with-dpf-in-mechanical
