Thank you so much AGAIN ! you are so kind for answering my question. so thanky to you, things are more cleared up, I have to dive more into Gmsh to refine my mesh. I am used to Ansys, Catia and FreeCAD and they have pretty advanced GUI for meshing... when I used Gmsh, I left almost everything to default… (Gmsh is powerful but not for beginners)kevinarden wrote: ↑07 May 2023, 15:42 I try with your mesh, and it diverges right away. You may have a mesh issue. I did it in 3D with brick elements, and it will run with high viscosity models.

Thank you for the report! I also checked the file and it was deleted ! I will never use that upload center again...Rich_B wrote: ↑07 May 2023, 22:09 Hello,
The original link to the simulation files doesn't work, it says 'deleted'. You could try compressing the files into archives. The forum allows up to 1 megabyte per attachment and up to three attachments per post. Posting your current simulation as a working example, including geometry and sif file, would be helpful
Thanks, Rich.
Unfortunately, I have overwritten the original files of this post (I believe); I will try to upload the new setup again,with a new mesh to see if that might work or not.
also, I know about the upload capability of this website, but 1Mb was too small for the entire simulation; mainly bec of geometry/mesh file; and i thought sending only pieces of the folder, is not nice (personally, I have trouble following examples in github, since there is no geometry and as a new comer, I don't know my way around them. It would have been nice, if I could run the examples on my computer, and gradually changing them to learn from them, but i don't know how to run them from github)
