Hope you are doing well.
I am new to SOFA but really eager to learn SOFA.
I want to simulate a soft robotic arm inside liquid environment (water) while the actuation of the soft body of the arm is based on heat transfer. My simulation should have collision property and also control of the arm by the heat transfer actuation.
I will be appreciated if you help me with that.

Hi @asalimil ,
Welcome on the SOFA forum. Sorry for our delay and thank you for your interest in SOFA!
First of all, when you have a new question (like you have here) please do not hesitate to open a new forum thread.
Regarding your question, there is not in the SOFA public version a class computing such liquid environment. I know there was some years ago a Buoyant force implemented in a private code. I am working on making these codes open but this will take time. Let me know if you feel confident to implement your own 😉

Dear Amir !
Thanks for your interest in SOFA.
What you describes seems very ambitious. Do you plan to model the heat transfer and the coupling of this heat transfert with mechanical properties ?
For forces generated by water, we plan to model buoyant, truss and drag forces in the coming months in SOFA. But this is not yet available. Let me know if you think you can help us with the implementation.

Thank you so much for the message. I am really interested in using SOFA in my projects and I will learn it and plan to develop if it is necessary.
I hope the fluid simulation is developed very soon and I am eager to help SOFA group with developing this environment. Please let me know how I can contribute to this simulation.

Dear Prof. Duriez,
Thank you so much for your reply.
I agree with you. This would be very ambitious.
I am planning to model the heat transfer inside a cubic soft object in a fluidic (water) environment. The heat should contribute to the deformation of this soft cube.
I will be glad if I can help you with this implementation.

Great, it’s nice to see your involvement in the SOFA project.
Do not hesitate to have a look at the DiffusionForceField available in SOFA!

Do you see the “SPHFluidForceField” ?
Behnam Binesh8 June 2019 at 8 h 33 min #13608
I never heard about that. Thank you for your suggestion.
I will try it and update you.

There is also a plugin called SofaEulerianFluid 2D & 3D.
I’m not sure it is very active yet but if you try it please tell us and in all case it is probably a good starting point for fluid simulation.2 July 2019 at 19 h 39 min #13894
Thank you for sharing this plugin.
I will try it and let you know.
