Python Result example: Plot Young Modulus on elements

Here's an example using the Young Modulus. It the adapation to Mechanical of an example provided in the PyDPF documentation: https://dpf.docs.pyansys.com/version/0.8/examples/00-basic/12-get_material_properties.html#sphx-glr-download-examples-00-basic-12-get-material-properties-py

Model is made of two cubes in contact, with two different materials defined:

Insert a Python Result object:

Copy-paste and adapt the following code:

def post_started(sender, analysis):# Do not edit this line
    define_dpf_workflow(analysis)
 
def define_dpf_workflow(analysis):
    import mech_dpf
    import Ans.DataProcessing as dpf
    mech_dpf.setExtAPI(ExtAPI)
    # Define datasource and get mesh
    dataSources = dpf.DataSources()
    dataSources.SetResultFilePath(analysis.ResultFileName)
    model = dpf.Model(dataSources)
    mesh = model.Mesh
    # Get material properties and especially the Young Modulus values
    mats = mesh.GetPropertyField("mat")
    mat_prop = model.CreateOperator("mapdl_material_properties")
    mat_prop.inputs.materials.Connect(mats)
    mat_prop.inputs.properties_name.Connect("EX")
    mat_prop.inputs.data_sources.Connect(dataSources)
    mat_field = mat_prop.outputs.properties_value.GetData()[0]
    # Create a new field (elem number, Young Modulus on element)
    new_field = dpf.FieldsFactory.CreateScalarField(mesh.ElementCount)
    new_field.MeshedRegionSupport = mesh
    new_field.ScopingIds = mesh.ElementIds
    new_field.Location = 'Elemental'
    matids = [mats.GetEntityDataById(elem_id) for elem_id in mesh.ElementIds]
    young_modulus = [mat_field.GetEntityDataById(matid[0])[0] for matid in matids]
    new_field.Data = young_modulus
    # Forward field for plotting
    forward = dpf.operators.utility.forward_field()
    forward.inputs.field.Connect(new_field)
    dpf_workflow = dpf.Workflow()
    dpf_workflow.Add(forward)
    dpf_workflow.SetOutputContour(forward)
    dpf_workflow.Record('wf_id', False)
    this.WorkflowId = dpf_workflow.GetRecordedId()

Connect the result and evaluate it:

The returned plot is:
