Tagged: 64_bits, Linux_ubuntu, Plugin_other, SOFA_2006
Hello everyone,
I am working a lot with sofa and hyperelastic materials and having quite good result. I am also enjoying the Mesh partitioning tool for multimaterial simulation.
The fact is that, it works only for linear elastic forcefield, because the localstiffnessfactor “variable”list is present only there. So i will appreciate if this varialble is present also in TetrahedronHyperelasticFemForceField environment. In particular, I have some materials tha behaves like Mooney Rivlin and some like Neo-hookean. So for Neohookean, it will be just one variable list (for the coefficient mu) for Mooney rivlin two variable list one for (C01 and one for C10), i calculate my bulk modulus in another way and for polymers is quite the same for everyone.
As i am very new in Sofa, I am not such a developer, can anyone show me which is present the C++ code related to localstiffness factor list? and in which part of code of TetrahedronhyperelasticFemForceField i have to insert it?
then i will play by myself ahahah. Thanks a lot in advance.
Hey @pasquale94
Indeed, it is homogeneous hyperelasticity for now. It’s lack of time on the developer side. If you feel up to implementing it, it would be most welcome.
