I am doing a flow analysis of solar panels and their supporting structure. It involves parts of supporting structure which are as small as 8e-04 thickness and the whole enclosure is of about 70m x70mx 10m. The problem is when i try to mesh them using edge sizing for very large edges(~10m) and very small ones with appropriate element sizes it consistently throws up three errors:
Ansys mesh the surface mesh is intersecting or close to intersecting making it difficult to create a volume mesh please adjust the mesh size or adjust the geometry to fix the problem.
A mesh could not be generated using the current meshing options and settings
The mesh generation did not complete due to poor quality elements or incorrect input.
I tried pinching, virtual topology as well as keeping the element size and max face size very low(which sometimes freezes the computer) to no avail. I am wondering whether i could remove the small edges but the thing is i intend to perform stress analysis using the flow data which probably could affect the results Any suggestions would be appreciated. Thanks.
