Cylindrical grid in 3D
Hi there,
MeshMaker provides the possibility to very easily create a cylindrical axis symmetrical mesh with RZ2D keyword potentially combined with LOGAR.
Does anyone knows please if there is already an existing mesh generation software compatible with TOUGH able to easily create a cylindrical mesh with elements explicitly discretised in the 'theta' direction? Somehow a 'RZ3D'?
Thank you in advance.

Hi Ludo,
I do not know of any mesh generator specifically designed to create a cylindrical mesh with theta discretization. You could try AMESH, a free program that creates simple Voronoi grids for TOUGH. You would have to specify the nodal coordinates with (r,theta) geometry, and AMESH would do its best to create the grid. A much more elaborate program WinGridder, which is not free, but is licensed through LBNL does have the option to create (r,theta) regions in grids, which are known as well refinements. I have never created a stand-alone RZ3D gird, but I have put in this local refinement. You specify how many theta sectors you want, and how many radial rings, and the radial increments. I have found that WinGridder has a steep learning curve, but it is a very powerful program.

Thank you Christine. I had a look at AMESH and Wingridder and it doesn't look like they can do what I want. I will probably code a modification of MESHMAKER...

Dear Ludovic, you can do it using voro2mesh in a very simple way. (https://site.unibo.it/softwaredicam/en/software/voro2mesh) and visualize grids and simulation results using TOUGH2Viewer (https://site.unibo.it/softwaredicam/en/software/tough2viewer).
I attached here the voro2mesh manual.
You have just to define the seed points of the grid.

Thank you very much Stefano. Will definitely have a look!
