Icepak fluid region mesh

[ghost]

I am in process of running a board level simulation using pyaedt for Icepak, I am facing issue with meshing , details of which can be found below

1. For meshing when manual method is turned off (icepak.mesh.global_mesh_region.manual_settings= False) I can see mesh both in materials as well as region created(fluid domain)

2. When manual setting (icepak.mesh.global_mesh_region.manual_settings= True ) is turned on and maximum element sizes are given using icepak.mesh.global_mesh_region.settings["MaxElementSizeX"]="Xmm" and then updated using icepak.mesh.global_mesh_region.update() command to generate mesh , I can see mesh only in solid domain and not on air domain.

Script used for meshing can be found here

icepak.mesh.global_mesh_region.manual_settings= True
icepak.mesh.global_mesh_region.settings["MaxElementSizeX"]="3mm"
icepak.mesh.global_mesh_region.settings["MaxElementSizeY"]="3mm"
icepak.mesh.global_mesh_region.settings["MaxElementSizeZ"]="0.5mm"
icepak.mesh.global_mesh_region.Level = 2
icepak.mesh.global_mesh_region.update()
icepak.mesh.generate_mesh()

I am wondering whether some additional lines should be added to mesh airdomain or am i making mistake somewhere else.

Hi @BhagirathaSomayaji, thanks for pointing out this behavior. I was able to reproduce this and I will investigate (#4788).
In the meantime, you can use this as a workaround:

import pyaedt
icepak = pyaedt.Icepak()
icepak.modeler.create_box([0,0,0], [10,20,30])
icepak.mesh.global_mesh_region.manual_settings= True
icepak.mesh.global_mesh_region.settings["MaxElementSizeX"]="3mm"
icepak.mesh.global_mesh_region.settings["MaxElementSizeY"]="3mm"
icepak.mesh.global_mesh_region.settings["MaxElementSizeZ"]="0.5mm"
icepak.mesh.global_mesh_region.update()
icepak.mesh.global_mesh_region.global_region.object.solve_inside = False
icepak.mesh.global_mesh_region.global_region.object.solve_inside = True
icepak.mesh.generate_mesh()
icepak.close_desktop()

icepak.mesh.global_mesh_region.Level = 2 should not be used for manual mesh settings (#4789).

I tried above method, though I am able to create a box , mesh is not getting generated.

Commands i used are as below
icepak.modeler.create_box([-100,-50,-50], [120,120,120])
icepak.mesh.global_mesh_region.manual_settings= True
icepak.mesh.global_mesh_region.settings["MaxElementSizeX"]="1mm"
Icepak.mesh.global_mesh_region.settings["MaxElementSizeY"]="1mm"
icepak.mesh.global_mesh_region.settings["MaxElementSizeZ"]="0.5mm"
icepak.mesh.global_mesh_region.update()
icepak.mesh.global_mesh_region.global_region.object.solve_inside = False
icepak.mesh.global_mesh_region.global_region.object.solve_inside = True

I have recieved error message which is

PyAEDT WARNING: No mesh operation found.
PyAEDT WARNING: No mesh region found.
PyAEDT INFO: Mesh class has been initialized! Elapsed time: 0m 0sec

Do let me know your suggestion on this.

Hi, I just tried again and everything is working smoothly on my side. Please try to update pyaedt to the latest version.

If you still have any problem with the updated version, please provide the python and the AEDT version you are using.

Hi, I am using Ansys 2023R2 and 0.9.4

[lorenzovecchietti]

Can you try 0.9.5 that was just released? In the meantime, I'll test on 2023R2.
