Hi, currently I'm using cadfeko to build a rough surface model, it is a brick with a rough surface on the top, and the source is an equivalent spherical mode source (as shown in the figure).
I have many surfaces that are randomly generated by Matlab and imported to cadfeko by .stl file, and then I use feko to mesh it again, using coarse mesh. When I run feko solver, due to the roughness, some of the models fail due to the mesh error, such as " ERROR 3864: Inconsistent specification of the media in connection with the orientation of the normal vectors at connected mesh elements", " ERROR 120: Segmentation rules have been violated (triangle is too large)". Furthermore, because of the model size, some of the simulations also fail because of " ERROR 33467: Not enough memory available for dynamic allocation".
I have seen some of the solutions online, in which they said you can delete the triangle that causes the error. But in my files, there are two problems. First, I'm not quite sure how feko files store the model mesh. I use the university server to mesh the model, and when I transfer the meshed model from the server to my own laptop, the mesh is not there, so I cannot edit it. The second problem is that when I tried to mesh a small model on my laptop, although the meshed model contains many triangles according to the meshing info from the mesh menu, in the Construction/Meshes/UnknownMeshParts_1 there is only one triangle labeled as '0', so I cannot modify the triangles.
My question would be is there any way to solve the mesh error? And for the memory issue, is there any way to reduce its frequency of happening? Thank you.
