Dear all, I would like to ask for advice on a the following problem. I'm modeling tissue destruction in lungs, where tissue is initially modeled as a pre-stressed network of nodes connected by springs at equilibrium. Due to inflammation, some nodes are "lost" and the new equilibrium of the remaining nodes is computed, leading to increase in the stress level that will cause even more ruptures. An introductory review can be found, for example, here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4041120/
I was wondering which could be the best way to simulate that: I started creating a grid with networkx and discretizing the elastic equations on the nodes but soon I realized that I was replicating existing FEM code. I thought I could use sfepy for that, however, is it possible to remove nodes from the mesh during the computation? I tried to look it up in the documentation but I couldn't find anything explicit.
Thanks for any suggestion you might provide and thanks for this beautiful software!
With best regards,
Mario
