Contact Surface meshing issue
Posted: Wed Oct 07, 2020 12:21 pm
Hello,
An issue has surfaced regarding Contact Surface meshing and I have not found any information about it in this forum. Below is a description of the issue:
*I start from any 2D model including a Contact Surface, the model has already been meshed with a general mesh size (e.g. 0.1)
*Then I assign an unstructured mesh size on lines (e.g. 0.02) to the contour lines of the Contact Surface and re-mesh it.
*The resulting mesh does not change, i.e. it ignores the assigned size 0.02.
*After that I assign unstructured mesh size 0.02 on surfaces to the Contact Surface and re-mesh it.
*Now the mesh only changes at the end points of the Contact Surface, the rest of the surface and lines still ignore the assigned size 0.02.
*Next I close the GiD model, open it again, and without making any changes I re-mesh it again.
*After this, the entire contact surface is using the right size of 0.02 that I had assigned it.
I don't know if I'm doing something wrong, but I find it odd that without making any change (just closing and reopening the model) you get a different mesh.
Here I attach a simple example model.
Thank you.
