    I try use Netgen to mesh a composite geometry. Netgen can't directly use .stl file because there are always noconsistent errors of surface normal . So I transfer .stl file to STEP file by FreeCAD. But when I mesh the STEP file, it just gives the surface mesh, not volume mesh. How can I deal with this problem?

    Hello all, I meet a problem when I want to use Netgen to create 3D triangle mesh. I create the .stl file by another software and put in attached file. But when I input the file, it always show inconsistent faces. I change the facet normal but not works. Is there any other solution or other type of the input file can avoid the problem? Because when we use .stl file, it just include the vertices and facet normal information. When I draw a 1/8 sphere include another 1/8 cube/sphere/other geometry, the...

    I have create 1/8 sphere include another small 1/8 sphere by MATLAB and output the STL file. But when I want to import this geometry into NETGEN, there are always inconsistent triangles error. I know it's the problem of definition of the interface. I can't use netgen/ CSG to create geometry because my inner part geometry is not only sphere. Anyone could help me solve this problem? How to define the normal of interface in stl? Or maybe there's other way to merge two geometry?
