Mesh around an opening and other mesh-related queries
Posted: Thu Mar 14, 2024 5:58 pm
Hi Escolano,
I hope this message finds you well.
I have a cube with holes in one of its faces that goes all the way to the opposite face of the cube (images 1 and 2). As you can see in this image, I have a semi-structured hexahedral mesh. I want to concentrate the meshes along the edge of the holes but I can’t do it using the semi-structured hexahedral mesh. Now my questions are:
1- Correct me if I am wrong that meshes cannot be concentrated around the hole using the semi-structured mesh. The other option is to use tetrahedral meshes which allows for unstructured meshes and mesh concentration nearby a point or line. But the tetrahedral mesh has fewer integral points than the hexahedral mesh and if it is possible, I prefer the hexahedral mesh.
3- Regardless of the capabilities of GID, what is your software recommendation to generate very complex meshes and then import them into GID? How can I make meshes like this (see image 3)? I have gone through the manual but the meshing section guidelines doesn’t seem to work for my model
4- My 4th question is irrelevant to the above ones; how can one mesh a circle like any of the below images this in GID? (images 3-7)
5- How can one improve meshing in the surface of a cylinder? (see image 8). Make it Radial like the images above (image 3-7)
I am Using GID 16.0.6. Images are attached in a .rar file. Many thanks for Your time, support and kind consideration.
Best regards,
Hamed Sadaghian
