Multizone will not form 3D elements
I have been trying to use the multizone method to get a hex mesh with an inflation layer for an external flow problem.
I am just trying to simulate flow around a horizontal and vertical pipe and their boundary interaction. I want to have an inflation layer around each pipe to better resolve the boundary layer.
When I try and use the multizone method, errors come up stating either:
- multizone mesh failed during meshing of blocks
- the 3D fill could not generate any volume elements
I have tried cutcell as well but the inflation layers do not generate.
Any advice on how to handle this issue would be greatly appreciated.
This is the model with the highlighted regions as the pipes.
