I have in the region of 16E6 nodes and it takes ages for Mesh Generation as well as the solution when analysing the domain around a truck.
How do i go about changing the node and element count? Would it also be ideal to chnage the element size from 0.1m to 0.5m? Thanks |

The alternative is to borrow or buy a cluster to run your job in parallel. Assuming that this is a turbulent, steady state simulation, you should be able to solve this in a reasonable time on 50-100 cores with Ansys Fluent, Star CCM+, or OpenFOAM. I have clients with clusters of this scale running problems up to 100M cells in steady state on a regular basis. If, however, you are doing LES or some other transient analysis, I think that you need to go back to the drawing board and reassess exactly what you are trying to accomplish. |
