How to create a 3D mesh with different element sizes in different regions?
Posted: Mon Mar 04, 2024 9:09 am
I am new to GiD and I am trying to create a 3D mesh for a fluid-structure interaction problem. I have a geometry that consists of a solid domain and a fluid domain, and I want to use different element sizes in different regions of the geometry. For example, I want to use smaller elements near the interface between the solid and the fluid, and larger elements in the far field. I have read the manual and the tutorials, but I could not find a way to do this. I have tried to use the mesh size function, but it seems to apply the same size to the whole geometry. Is there a way to define different mesh sizes for different regions or layers in GiD?
