Hello,

 

I am trying to export deformation, stress, and strain data at different substeps using python in Ansys. This is my current code which exports the selected substep.

I am trying to create a loop that goes through each of the substeps and exports the data from each substep into a folder based on the data type(deformation, stress, strain). 

 

# ----------------------- READ ME FIRST -----------------------

# MAKE SURE THAT THE USER DEFINE RESULTS HAS LOC_DEFX ***FIRST***

# Second will be LOC_DEFY, third will be LOC_DEFZ

 

#input the row number below (for naming)

row_number = '400'

 

# input the file path for where you want the files to export to 

# (do not select 13mm or 18mm folder, stop at skin test folder)

save_location = r"C:\User\Downloads"

 

# No need to edit anything below this point

counter = 0

for analysis in ExtAPI.DataModel.Project.Model.Analyses:

    for result in analysis.Solution.Children:

        

        if result.GetType().Equals(Ansys.ACT.Automation.Mechanical.Results.DeformationResults.TotalDeformation):

            fileName = "{}\Deformation [D]\{}_D.txt".format(save_location,row_number)

            result.ExportToTextFile(fileName)

        if result.GetType().Equals(Ansys.ACT.Automation.Mechanical.Results.StrainResults.EquivalentElasticStrainRST):

            fileName = "{}\Strain\{}_SN.txt".format(save_location,row_number)

            result.ExportToTextFile(fileName)

        if result.GetType().Equals(Ansys.ACT.Automation.Mechanical.Results.StrainResults.MaximumPrincipalElasticStrain):

            fileName = "{}\Principle Strain [PS]\{}_PS.txt".format(save_location,row_number)

            result.ExportToTextFile(fileName)

        if result.GetType().Equals(Ansys.ACT.Automation.Mechanical.Results.StressResults.EquivalentStress):

            fileName = "{}\Stress [SS]\{}_SS.txt".format(save_location,row_number)

            result.ExportToTextFile(fileName)

        if result.GetType().Equals(Ansys.ACT.Automation.Mechanical.Results.UserDefinedResult):

            if counter == 2:

                fileName = "{}\Z Coordinate of Deformation [ZLOC]\{}_ZLOC.txt".format(save_location,row_number)

                result.ExportToTextFile(fileName)

                counter = 3

            if counter == 1:

                fileName = "{}\Y Coordinate of Deformation [YLOC]\{}_YLOC.txt".format(save_location,row_number)

                result.ExportToTextFile(fileName)

                counter = 2

            if counter == 0:

                fileName = "{}\X Coordinate of Deformation [XLOC]\{}_XLOC.txt".format(save_location,row_number)

                result.ExportToTextFile(fileName)

                counter = 1

Hi 

I request you to post scripting (ACT/python) related queries in the developer forum.

You can go through following script to loop it through different substeps.

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

 

 

• Store link to solution

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

• Obtain list of time sets

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

• Loop through data sets

  1. for DataSet in range(len(DataSets)):

• Define display time

  1. DisplayTime=DataSets[DataSet]
  2. UnitTime='[sec]'

• Insert result and evaluate

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

• Export result to text file

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

 

 

Hope it helps.

Thank you

Hello,

Thank you for your quick reply. When I try this, I receive the error message that "Solution Information" object has no attribute "Display Time". Could you please advise me on why this is occuring?

 

Thank you.
