Thanks for your help.
For the mechanical properties, do you mean materials? The actuator bellow is made of silicone. So I set the youngModulus = 1700kPa and poissonRatio = 0.3 in TetrahedronFEMForceField. The time step is 0.02 and object size is around 50mm length. When I tried timestep/100 = 0.0002, the problem is still existing.
Very appreciate your help and sorry to bother you again.
Do you have any suggestion to solve my SparseLDLSolver issues? I have rebuilt whole system. But it doesn’t help.
Also, for the container issue. This not only happened on Soft Robot tutorial, but also other mesh files either made by myself or from others uploading in the forum. I…[Read more]

Really appreciate for your fast responses and time for testing my scene.
1. sorry for my stupid mistakes. What I mean not working is that an error from SparseLDLSolver keeps reporting:
[ERROR] [SparseLDLSolver] Failed to factorize, D(k,k) is zero, which has been asked in an old post.…[Read more]
This is scene code: https://github.com/duanmu23/SOFA-bellow.git
I just tried to apply a distributed pressure on the surface of the actuator. But it seems not working. Also, can you tell me what is the meaning of @.. and @. in mapping?
Thanks for your time helping me.
Also, I have issues with SparseLDLSolver. I have checked the thread . My problem is the same that the error “failed to factorize” reported during simulation. The Metis is successfully built in Cmake. There is a line in cmake: “metis was found, SparseLDLSolver will be built”, and the address for Metis_DIR is sofa/build/cmake . Because I…[Read more]
Thanks for helping me.
At the end, I added entry in cmake to install the plugin. Meanwhile, I copied the all the file in lib and include documents in costumed version of SOFA provided on SoftRobots website into the src file 19.12 SOFA. Then finally successfully installed the plugin.
Can I ask another question about using the SOFA?…[Read more]
Can anyone help me with the plugin installation?
I followed the instruction on softrobots plugin website by adding the path of softrobots and STLIB source file to the entry SOFA_EXTERNAL_DIRECTORIES in cmake. But in the documentation on SOFA website, it says extra lines need to be added in cmakelist, sofa_add_plugin(plugins/ …)…[Read more]
