How to export Animations from Mechanical in batch from WB script?

Rohith Patchigolla

I have a Modal analysis system with 100 deformations. I want to export all the animations in batch via WB scripting. All my deformations are grouped in a folder whose id can be used as an input to locate the result objects.

Here is an example script. You can run in from WB --> File --> Scripting --> Run Script File. You can track the time taken for each animation in the log file (WB --> Extensions --> View Log)

#Example script to export animations
mechScriptCmds = """
###User Inputs###
import os
import time 

#Get the right analysis to store the data
UserAnimPath = DataModel.AnalysisList[0].WorkingDir 
GroupId=49

##################
Graphics.ResultAnimationOptions.NumberOfFrames=30
Graphics.ResultAnimationOptions.Duration=Quantity(2,'sec')
settings = Ansys.Mechanical.Graphics.AnimationExportSettings(width = 1920, height =1080)
expFormat=GraphicsAnimationExportFormat.MP4
Group=DataModel.GetObjectById(GroupId)

for i in range(0,len(Group.Children)):
    begin = time.time() 
    myResult=DataModel.GetObjectById(Group.Children[i].ObjectId)
    AnimPath=os.path.join(UserAnimPath,myResult.Name + ".mp4")
    ExtAPI.Log.WriteMessage(AnimPath)
    myResult.ExportAnimation(AnimPath,expFormat,settings)
    timetaken = time.time() - begin
    ExtAPI.Log.WriteMessage("Time taken for animation " + str(i+1) + " is :" + str(timetaken) + " s ")

#Assuming we are working on 1st system in WB Project page
#Get the right system to send the Mechanical script commands.
mySys = GetAllSystems()[0]
model = mySys.GetContainer(ComponentName="Model")
model.Edit(Interactive=False)
model.SendCommand(Language="Python", Command=mechScriptCmds)

One can also do this export directly within Mechanical after the model solve is completed using Python Code object, with "After Post" callback. The script can be found below.

def after_post(this, solution):# Do not edit this line
    """
    Called after post processing.
    Keyword Arguments : 
        this -- the datamodel object instance of the python code object you are currently editing in the tree
        solution -- Solution
    """


    # To access properties created using the Property Provider, please use the following command.
    # this.GetCustomPropertyByPath("your_property_group_name/your_property_name")

    # To access scoping properties use the following to access geometry scoping and named selection respectively:
    # this.GetCustomPropertyByPath("your_property_group_name/your_property_name/Geometry Selection")
    # this.GetCustomPropertyByPath("your_property_group_name/your_property_name/Named Selection")
