Hello,
I am dealing with a non-linear problem in hyperelasticity involving very large deformation. So the elements rapidly become excessively distorted which causes convergence problems.
What are the current tools available within FEniCS to perform remeshing ? I found a link to : https://github.com/meshadaptation/pragmatic on this forum. Has someone experience and examples with it ?
Otherwise, are there other possibilities (alternatives to remeshing) to overcome this difficulty, like distortion control ?
Many thanks in advance,
Claire
