Automating Surface and Edge guided Element Orientation in Mechanical

Hello,

I am working on a hydrogen diffusion project, wherein I have a microstructure with multiple grains and inflated grain boundaries that are the diffusion pathways within my structure.

Diffusion within these inflated grain boundaries are anisotropic. As such, I need to assign element orientations for each grain boundary. I do not want to assign these orientations to the other bodies in my structure. I have been doing this manually within Mechanical using the surface and edge guide:

My question is that if I can automate/script this element orientation process. I know the names of the bodies/geometries that need orientations. Is this possible to do? Enclosed is the CDB of the microstructure from the photo above. Please let me know if any extra information is needed :smile:

Thank you for your time,
Bhanuj

    Hello,

    I think you could investigate using Named Selections for automatically applying the Element Orientation

    In the example below, 3 NS have been created for body, face and edge:

    You can automatically create and setup the Details window following these lines:

    elemOrient=ExtAPI.DataModel.Project.Model.Geometry.AddElementOrientation()

nsbody = ExtAPI.DataModel.GetObjectsByName("MYBODY")[0]
nsface = ExtAPI.DataModel.GetObjectsByName("MYFACE")[0]
nsedge = ExtAPI.DataModel.GetObjectsByName("MYEDGE")[0]

elemOrient.BodyLocation=nsbody
elemOrient.SurfaceLocation=nsface
elemOrient.EdgeLocation=nsedge

    After executing those lines, you should see a new Element Orientation object created with its proper assigment

    Best Regards
