Before asking, Thank you for your kind answer about my preivous question.
It was so helpful to me.
I am working on developing 3D FEM application related with neutronics problem.
Following is my first question
Today I made 3D domain, that has physical volumes. But I saw that the jacobian of certain element is zero.
Because of a element that is consist of 4 nodes which are located on same plane!
Why does GMSH produce such a strange element? Does it due to my fault in making GMSH input?
Of course, I can eliminate that element by giving certain condition to my code, it seems to be strange.
Please tell me in detail, if the reason is related with my input.
My second question is associated with defining volume. I understood that the orientation of surfaces which will
constitute the volume should be consistent. But if we want to make a cube or hexahedron volume, the following order of
surface index is OK? I mean that writing index(upper plane), index(lower plane), index(left plane),.... , not continuously.
Please tell me in detail. Sorry for bothering you.
