Posted:

I have 2 related question:

I understand that this is the maximum size of 3D mesh element. But how exactly the mesh is defined? Does rxd create the mesh automaticaly on each x,y,z direction assuming that each element of the mesh has the area of dx?

Thanks for your help!

I have 2 related question:

- What is the difference between rxd and crxd?

- What exactly define dx param for Region when I use:

Code: Select all

`rxd.set_solve_type(dimension=3)`

Thanks for your help!
