      The following function can be used:

      1. def ExtractMassInfo():
      2.     '''
      3.     Extract masses for all bodies and point masses
      4.     '''
      5.     listExportMasses = []
      6.     # looping through geometry to extract name and mass of unssuppressed bodies
      7.     for part in ExtAPI.DataModel.Project.Model.Geometry.Children: 
      8.         if part.Suppressed is False: 
      9.             partType = part.GetType() 
      10.             if partType == Ansys.ACT.Automation.Mechanical.Part: 
      11.                 for body in part.Children: 
      12.                     if body.Suppressed is False: 
      13.                         bodyName = body.Name 
      14.                         bodyMass = body.Mass 
      15.                         bodyMassValue = round(bodyMass.Value, 5) 
      16.                         bodyMassUnit = bodyMass.Unit
      17.                         bodyCentroidX = body.CentroidX
      18.                         bodyCentroidXValue = round(bodyCentroidX.Value, 5)
      19.                         bodyCentroidXUnit = bodyCentroidX.Unit

      Hi Pernelle,
      I add this python code to Properties Provider. I set up the Target Callback as Get Post Commands. However, I can not get the mass

      Could you show me how to run the code? or Do I need to modify the Target Callback?

      Hi @Huy.Truong , the property provider tab is to modify the details view of the Python Code object (ie add inputs and/or outputs parameters). It doesn't get executed when the Python Code object is triggered. Code for the Python Code object should be entered in the "Script" tab. Please note that the function I provided above is to be executed from the console. Also, "Get Post Command" callback is used to send MAPDL code for postprocessing so it is not suited in your case. I'd recommend having a look at this section of the help, it would help you.
