Hi,
I try to do some stress analysis with OpenFOAM. For the first shot I used the "stressFemFoam" solver, which works well. Additionally I want to analyse a case with prestressing. I think for that I have to add an explicit term "d/dx_j(sigma_ij)" into the FEM equation. Is there a functionality to do so in OpenFoam? (I just found the explicit functions "grad", "elementGrad", "ddt") Can anyone give me some advice? Ralph |

Hi,
I know your post is very old, but I'm facing the same problem now. For I have poor convergence with the implementation done in stressFemFoam, I want to use prestressing, but I'm not quite sure how to implement divergence of a tensor for finite elements. Did you ever solve it? Regards Stefan |
