I am working on a project for school that involves replicating the human heart. I came up with a composite that would hopefully replicate it, and all I want to test is the strength of the composite. I have experienced issues such as walls going through each other, it expanding like a balloon, or the simulation flat out fails. I have tried linear, non-linear, and hyperelastic models. I have posted this question before and have gotten responses, and although they have helped somewhat, they haven’t gotten to the root of my problem. I am not skilled in Simscale by any means; I am practically clueless, and all I want to test is whether my material is strong enough. I will provide links to my project and previous forum posts to help fill in any blanks. It would be great to have another point of view to help find a solution.
Thanks.
Here is the link to my previous forum discussion that will keep you up to date
Commenting exclusively on the “walls going through each other” comment: a pair of faces will only account for one another if they are part of a contact (either a linear contact such as bonded and sliding, or a physical contact if you have nonlinear studies).
If two faces that are not defined as master/slave assignments of a contact happen to touch in the simulation, they will ignore each other. The solution for this is fairly simple: you just have to create the appropriate missing contacts.
Now, whether or not the amount of deformation that you are seeing is expected, that depends on material properties, loads, and how you are constraining the parts of the assembly.
