Hello,

My question is about how a hyperelastic model can be implemented in foam-extend?
The displacement gradient is needed in hyperelastic models.
I was starting with other rheology laws such as PronyViscoelastic model but in this model ((fvc::gradU)) is not used. When I define deformation gradient tensor from volTensorField class I get errors.
Could anyone provide me the solution?

Thanks a lot
