I want to implement the linked article with sofa
Do I need to code or there are ready modules that I can use?
How can I write and modify the FEM governing liver equation in XML with sofa(apply force to liver and deform it)?
I’m a new to SOFA.I have an obj liver file and I want to implement it based on FEM in sofa and apply force to this liver with a tool using sofa.
Would you please help me introduce some paper and sample code about it?
