    Hi Ishan,

    I looked more closely at the Rodriguez growth model and some of the literature papers describing its finite element implementation but I regret that I am unable to figure out a general finite element implementation of this framework that would work for arbitrary constitutive relations for the growth. This prevents me from creating a plugin that could easily be modified by any user to match a desired growth model. The main problem is the evaluation of the tangent stiffness matrix (the elasticity tensor) when the growth is either strain or stress-dependent, isotropic or anisotropic, using an elastic material that is either isotropic or anisotropic, and where one or more structural tensors defining the material anisotropy may evolve with growth.

    I realize that this may limit your options. Maybe you can find some paper that provides a sufficiently detailed finite element method for the specific model you need to use.

    Best,

    Gerard

    Hi Gerard,

    Could you send me the files that you have prepared?
