Calculation on two meshes
In my solver I have to do Biot-Savart, which are NumberOfCells² operations. That takes time. On the other hand, the mesh has to be fine enough for the simulation to be correct.
That is why I am thinking of calculating with two seperate meshes: (1) fine mesh for Navier-Stokes Eqn (2) a coarse mesh for Biot-Savart Are there any examples / predefined functions for working with two meshes and for interpolation between them? Thanks a lot!!! |
I already solved the problem, following this explanation:

Actually the blockMesh utility understands the "-region" option, so that you do not need to copy meshes from one directory to the other. Also decomposePar and e.g. funkySetfields know about the "-region" option.
