Dear Hugo,

Thank you for your reply!

This new mechanism could be extremely useful for dynamics randomisation. I am going to give it a try. Thank you and all the other developers’ great effort! I will close the post now.

Best wishes,
Owen

Hi @hugo

I am sorry to bother you. I guess you are very busy at the moment but I would like to know if there is any recent update on updating parameters in FEMForceFields like ‘TetrahedronFEMForceField.youngModulus’.

Thank you,
Owen

Hi,

I have resolved the problem by installing a Ubuntu 18.04 virtual machine. Now MOR is running smoothly. Thus I am going to close this post now. I want to go a big thanks to Olivier for returning to Python2 is the right thing to do to solve the problem.

Best,
Owen

Hi @olivier-goury,

Yes, I agree that going back to Python2 could solve the error. The only reason I choose to use Python3 is that I found it difficult to install PyQt4 with my current version of Qt5, while PyQt5 only supports Python3.

If I understand it correctly, PyQt is for the GUI so it is essentially optional for the plugin. I am wondering…[Read more]

Update: the syntax error seems to be fixed after I changed originalScene = r’$ORIGINALSCENE’ to originalScene = r”$ORIGINALSCENE” in the phase1_snapshots template.

However, this ‘fix’ might not be correct as I got a new error:

Hi @Hugo,

Sadly, I am experiencing the same problem described in this post. As you mentioned earlier ‘This is due to the fact that the constraint resolution has no CUDA version (CudaVec instantiation) in the open-source version of SOFA. However, it does exist in some private plugins.’, do you refer to the SOFA Multicore-GPU plugin? If so, I think…[Read more]

Hi @hugo

I am trying to use the Ogden model for my simulation as well. I am very pleased to see the TetrahedronHyperelasticityFEMForceField contains Ogden, but I am struggling to set the parameters.

As you mentioned in your previous reply, in Ogden.h:
Real k0=param.parameterArray[0];
Real mu1=param.parameterArray[1];
Real…[Read more]

Hi @hugo,

I feel kinda stupid to waste your time on fixing this tiny error… However, I have one more question to ask about BilateralInteractionConstraint if you don’t mind. I found this page explaining the Args:…[Read more]

Hi @secretdevil

Thank you for your reply!

I have corrected the case of “Constraint” as Hugo suggested, and then I don’t have this error anymore. I am sorry that my code is a bit messy… Even though I don’t fully understand how the templates work, I think the mechanical state was created in the children of rootNote. Like in Line 126 pneu2.createO…[Read more]

Hi JN,

I tried the first suggestion and it works! You have really made my day. Thanks a million!

Best,

Hi JN,

Thank you for your reply.

Yes, the full output seems a bit too long. I just redirected it to a text file. Please find the file in the link: https://drive.google.com/open?id=1sfmqP_7E-r6_ziejZGYV-lICtGFjVBaY

Many thanks,

Hi Hugo,

Thank you for your quick reply.

You solved my problems! Everything works perfectly in the console. I just realised that there is so much potential in using python script.

Thank you!

Regards,
Owen

Thank you Hugo. I am gonna close the topic now.

Hi Hugo,

Sure, after removing the borders, I used cellSize=’2′, facetSize=’2′, cellRatio=’2′, facetApproximation=’0.15′. However, they only give me an acceptable mesh because I am running SOFA on my laptop which is not very powerful.

I guess I will start with BilateralInteractionConstraint. Is there any example code I can take a look?

Many thanks,
Owen
