Hello all,
I am currently trying to implement a certain scheme for (time dependent) Maxwell’s equations.
Until now I was using BoxMesh to realise a mesh on the cube (-1,1)^3. For some time step I get the following result:
From theory and also from implementing an easier scheme like the Implicit Euler I know that the solution should be symmetric. In fact the solution becomes more symmetric when refining the mesh. I thus conclude that the issue is due to a lack of symmetry of the mesh.
I am therefore looking for a mesh on the cube (-1, 1)^3 which is symmetric with respect to the diagonal plane.
I would be happy about any kind of help. Thanks in advance.
