Hi
I'm on simulation of an elastic square prism. Results are obtained to some time, then the solver (solids4Foam) crashes. The reason is that the highlighted cell(s) shown in the figure below becomes concave. (Note: Fluid region mesh is shown only.) Is there any way for run-time mesh refinement according to skewness in order to figure out this difficulty? regards Ali Last edited by amuzeshi; July 16, 2019 at 15:36. |

I know that the two classes dynamicMotionSolverFvMesh and dynamicRefineFvMesh can be combined into one class[1]. However, as it is needed to compile a new solver and initialize the skewness field in its *.H file, there remain two main problems:
1- As solids4Foam does not obey solver-oriented programming discipline in regular openfoam, where to declare skewness? 2- How to declare skewness as -to the best of my knowledge- it is not a volScalarField. regards Ali Ref: [1] Adaptive Mesh Refinement with a Moving Mesh using sprayDyMFoam Last edited by wyldckat; August 3, 2019 at 21:53.

I know that OpenFOAM defines skewness for faces, not for cells. But I want to refine the mesh based on a user-defined skewness:
cell skewness = max [ ( thetaMax - 90) / 90 , ( 90 - thetaMin) / 90] |

Hi, have you been able to solve your problem? Is there anything you'd like to share?
Kind regards |
