Delete material in the Material folder inside Mechanical

Erik Kostson

How can we delete a material (say Structural Steel) in the Materials folder inside Mechanical?

Erik Kostson

This is not possible to do, either manually (say by RMB on that material in that folder and choose delete) or via pure mechanical scripting it seems like.

One way of doing this is though via wbjn workbench scripting inside the mechanical script console. The following sample code deletes the Structural Steel material in the Materials folder (and Engineering Data) of the first system in the workbench project (SYS).

import wbjn
ScriptCmds = """
system1 = GetSystem(Name="SYS")
engineeringData1 = system1.GetContainer(ComponentName="Engineering Data")
material1 = engineeringData1.GetMaterial(Name="Structural Steel")
material1.Delete()
"""
wbjn.ExecuteCommand(ExtAPI, ScriptCmds)
Model.RefreshMaterials()
ExtAPI.DataModel.Tree.Refresh()

To delete all of the materials except of one (matk called below):

import wbjn
model = ExtAPI.DataModel.Project.Model
materials=model.Materials.Children
matk="Structural Steel" # material to keep change as needed

for mat in materials:
    if mat.Name !=matk:
        name=str(mat.Name)
        print(name)
        ScriptCmds = """
system1 = GetSystem(Name="SYS")
engineeringData1 = system1.GetContainer(ComponentName="Engineering Data")
matd = engineeringData1.GetMaterial(Name="%s")
matd.Delete()
"""%name
        wbjn.ExecuteCommand(ExtAPI, ScriptCmds)

Model.RefreshMaterials()
ExtAPI.DataModel.Tree.Refresh()
