I want to simulate an elastic ring in 2D or an elastic hollow sphere in 3D. There are cells dividing in the ring/sphere. When the ring is full of cells, it will exert a contraction force on the cells. How to achieve? Thank you!
I would use FocalPointPlasticity Plugin (FPP). FPP will connect centers of mass of nearby cells with elastic link. However when your cells are dividing then you woudl need to manually break the links and reestablish then after the division happens. The reason for that is that you want links for form a "chain" where one segment of the "chain" connects nearby cells. What you do not want is to have a chain where a segment of a chain "skips" new cell that appeared as a result of the mitosis .
