Using SOFA CUDA

[Harris]

Hi,

I am making a simulation using CorotationalFEMForcefield and I would like to use SOFACUDA plugin.However, I see that this component (CorotationalFEMForcefield) is not implemented in CUDA.How can I use SOFACUDA in such a case?

Thank you,
Harris

Hi @hkomninos

Indeed the CUDA-based version of the class CorotationalFEMForcefield is not implemented, therefore not available. Writing codes using the NVIDIA toolkit is (really) far from trivial. If you want absolutely to use a corotational approach, you can go for the FastTetrahedralCorotationalForceField: it is not GPU compatible but it is an optimized version.

Otherwise you will find:

• CudaTetrahedronFEMForceField: linear elasticity
• StandardTetrahedralFEMForceField: hyperlastic materials
• CudaTetrahedronTLEDForceField: anisotropic viscoelasticity for soft tissue simulation

I hope this helps.
Best wishes,

Hugo

Hi Hugo,

Thank you for your answer.I will test the different approaches you mentioned.Also,I was thinking about Multithreading plugin,do you think it will help me in my scene(combining geomagic and carving plugin)?

Best,
Harris

Dear @hkomninos

As the plugin name indicates it, the Multithreading plugin allows to use parellelism methods (like TaskScheduler) in SOFA at different level of the simulation. It might need a bit of experience in SOFA to handle it, but do not hesitate to look at the included examples.

Best
