Hello, please ask you a question, that is, I use Maxwell stress to calculate the magnetic force of the permanent magnet in the magnetic field, but the grid has a great influence on the calculation results. I continue to encrypt the permanent magnet grid, the calculation results have changed, the grid is not convergent, what's the matter with it, how can this be solved, thank you |

In this simulation, we need three modules, magnetic field (AC/DC), solid mechanics , and ALE. the first module is able to obtain the spatial field distribution. the second module is used to achieve the deformation by the imposed magnetic field. it is noted that the maxwell stress should be applied as a boundary condition. the third module is employed to adapt the mesh to make sure the quality of the calculation. you have to determine which part is free, which part is fixed and define some prescribe displacement? |
