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!

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

Hi Hugo,

Thank you very much for your reply!

You are absolutely right about the meshes. The thin borders caused my problem. I have managed to simulate the actuator after I removed them. So thank you!

My next step is to simulate an assembly of two of this actuator. However, I couldn’t find a tutorial on how to define the connection between two…[Read more]

The link to the STL files was lost somehow… I hope this one works
