What are the main parameters of model material tuning? How do these parameters fit together scientifically?

Hello!
I am currently using SOFA to do crystalline lens simulation and now I have encountered some problems:

1. When the fixed constraints of the crystalline lens disappear, the speed of fall is very slow, is this normal, if not normal, what parameters should be adjusted?
2. After I adjusted the parameters in SOFA, I found its material is very soft when I imported it into unity. Why?

Hi @yangwxb

1. possibly yes, but this could be due to different reasons: a very fine mesh, a very small time step, a lot of contacts/constraints etc
2. I guess you mean that it looks soft with regards to the mechanical parameters you set. Have you checked your scene unit? (see Simulation unit : make sure your units are coherent #4441)

PS: if you did not so far, I would really like to insist that you take the free online training course

I watched the free online training course, but there are still many things I don't understand. Now I suspect that there is something wrong with my script. Could you please help me look at it? Why does it run at such a low frame rate?

hello!I will upload the grid model if needed.

Did you go though the article I referred @yangwxb ?
