How to automate pressure load on FSI faces in vibro-acoustics?

Erik Kostson

So say we have 2 named selections (NS), called fs1 and fs2. How can we loop through them and apply a pressure load and find the correct structural body only associated with that face/NS using scripting?

Below is one way of doing this (it uses and assumes that on the shared FSI face, we need to get the structural body and not the Fluid/Acoustic body with Water Liquid material, for the shared reference body):

model=ExtAPI.DataModel.Project.Model # refer to Model
analysis = model.Analyses[0]
solution = analysis.Solution
impLoadGrp = ExtAPI.DataModel.GetObjectsByName('Imported Load (A2) ')[0] # change as needed
geodata = ExtAPI.DataModel.GeoData
 
ans=model.NamedSelections.Children
for ns in ans:
    presload=impLoadGrp.AddImportedPressure()
    presload.Location=ns
    my_geob = geodata.GeoEntityById(ns.Location.Ids[0]).Bodies
    for myb in my_geob:
        my_treeb = ExtAPI.DataModel.Project.Model.Geometry.GetBody(myb)
        if my_treeb.Material != 'Water Liquid':
            presload.SharedRefBody=my_treeb

or if we have all of the FSI faces in one named selection instead (called here myfsi - change name as needed), then the below might help:

model=ExtAPI.DataModel.Project.Model # refer to Model
analysis = model.Analyses[0]
solution = analysis.Solution
impLoadGrp = ExtAPI.DataModel.GetObjectsByName('Imported Load (A2) ')[0] # change as needed
geodata = ExtAPI.DataModel.GeoData
 
ns=ExtAPI.DataModel.GetObjectsByName('myfsi')[0] # change name of NS as needed
nsids=ns.Location.Ids
for nsi in nsids:
    presload=impLoadGrp.AddImportedPressure()
    selection = ExtAPI.SelectionManager.CreateSelectionInfo(SelectionTypeEnum.GeometryEntities)
    selection.Ids=[nsi]
    presload.Location=selection
    selection=ExtAPI.SelectionManager.ClearSelection()
    my_geob = geodata.GeoEntityById(nsi).Bodies
    for myb in my_geob:
        my_treeb = ExtAPI.DataModel.Project.Model.Geometry.GetBody(myb)
        if my_treeb.Material != 'Water Liquid':
            presload.SharedRefBody=my_treeb
