Default Time-dependent solid case with hyper elastic model

Hi everyone,

Recently I started to work on an FSI project on aneurysm using pimpleFoam + solids4foam with the preCICE coupling interface. I struggled a bit with the solid mesh and model setup. Basically I want to test the solid case with solids4foam only first before doing any coupling. I simply copied the files from one of the hyperelastic tutorial cases and modified certain parts.

My question is, is it possible to run a time-dependent solid case with one of the current hyperelastic models (preferably mooney-rivlin)?

All the hyperelastic tutorial cases use steady state fvSchemes and my efforts to try hyperelastic model with time-dependent configuration have been fruitless (solver crashing either during setup for GAMG and some time into simulation for PCG).

Also, is there any on-going development for a 5-parameter Mooney-Rivlin model? If not, is it difficult to implement one myself? I had some luck with implementing a BC in OpenFOAM.
