Hello Krishanu:
The error is made when you define the line/surface. You don’t have to check
the mesh file or each mesh element but the .geo file.
For example, here my line loop defines the surface bounded by vertex in
the order of [3.7,8,4], but I defined my line as the following.
So when I
Hello Jane,
Thanks for the response. I understand why there could be an issue with the
ordering. But I am using the GUI of Gmsh and the mesh created has about 400
elements. So it is a little difficult to manually check the ordering of the
vertices of each element. Do you know if there is any
Hello Krishna:
I had this issue before. It just means that when you select mesh entities
(vertex) to form a surface, you have to pay attention to the order of which
entity goes first, second,... it would be clear if you look at the geometry
txt file.
Best regards

Hello Paras,
Thanks for your response. I have been using the GUI of Gmsh to generate the
mesh. Do you have any suggestions about what to do in Gmsh to avoid the
negative volume issue?
Do meshes generated with Abaqus, are able to avoid the above-mentioned
issue of negative volume?
Thanks in
I use the .inp format of Abaqus, since my code relies on material-IDs which
(in my limited experience) are easy to handle with .inp format. I generate
meshes using both GMSH (here as you mentioned, one needs to be careful to
add curves/surface parts in the correct order to avoid negative volumes)
I am wondering what meshing software produces output files that would work
best with deal.ii. I have tried Gmsh, but it seems when this mesh
(generated by Gmsh) is imported in deal.ii, it is facing the issue of
negative volume fraction of a cell (could be because of the order of nodes

Thank you for your input! That was my first attempt at tackling this. However,
I run into problems with the line
