Hi @Hugo,

Have you tried anything? Is this also happening?

Thanks,
Jake

Hi @Hugo,

It’s nice of you!

The address of full mesh is https://drive.google.com/file/d/1PEEx5a3D00HgKDWi4r_PX2-z64McAhj-/view?usp=sharing.

It’s just a cylinder.I want to divide my structure to arbitrary parts.

I look forward to hearing from you!

Thanks,
Jake

Hi @Hugo,

I only used the CLIP of Paraview to do that.But this wrong happend.

Have you ever met the same problem when you use Paraview to divide structure?
Or can you tell me how to use Paraview to divide structure?

Thanks,
Jake

Hi @Hugo,

The address of this new part is:
https://drive.google.com/file/d/1wYrfe6tLQG3b68CTm2gld_JmD47BuK_W/view?usp=sharing

You can try again.

Thanks

Hi @Hugo,

Yes, I think I clipped mesh including tets.

When I try to load new part (used Paraview to divide), there are some wrong FEM.

The address of this new part is:
https://drive.google.com/file/d/1wYrfe6tLQG3b68CTm2gld_JmD47BuK_W/view?usp=sharing

Not only was there an error loading(you can try to load it in sofa), but it was also obvious that there was an issue with the lower half.

Do you know how to clip it correctly?

Thanks,
Jake

Hi @Hugo

I have found the methods to solve my problem.Thanks for your help.
What’s more, I can load test_cut.vtk(exported by Paraview) in Sofa.But when I use SubsetTopologicalMapping to connect test_cut.vtk with its main part,the Sofa’s warnning message is:
[INFO] [SubsetTopologicalMapping(SubsetTopologicalMapping)] TE: 925->0/925

I guess it’s because that I use Paraview’s CLIP to segmented structure.Do you use Paraview’s CLIP to segmented structure?And have you met such problems?

Thanks
Jake

Hi @Hugo,

1. Maybe there are some wrong with SOFA.I will try to open it when I reset SOFA.

2. But this example is the use of SubsetTopologicalMapping.What I want to know is its writing, not its usage.Or is there anything wrong with my understanding?

Thanks,
Jake

Hi @Hugo

1. cylinder0603.vtk is generated by GMSH and I have no trouble to load it.But the other file, test_cut.vtk(exported by Paraview), can not load by Sofa.
The address of test_cut.vtk is https://drive.google.com/file/d/1z4ZISpgYYPFyD1TazxWH5jEORAWb8r31/view?usp=sharing.
Can you help me see what’s wrong?

2.The version of SOFA is v19.06.

3.I want to creat a new compnent of SOFA to select ROI,rather than to use SubsetMapping to select.But I don’t know how to do.I want to try to construct the components I need from the components that Sofa already has.Do you have such examples?

Thanks,
Jake

Hi @Hugo，

1. The mesh files are included in the links below:
https://drive.google.com/file/d/1PEEx5a3D00HgKDWi4r_PX2-z64McAhj-/view?usp=sharing https://drive.google.com/file/d/1kRPi-rKh5UgqujKEyQizchUlOk_cqIW5/view?usp=sharing https://drive.google.com/file/d/1z4ZISpgYYPFyD1TazxWH5jEORAWb8r31/view?usp=sharing

Among them,the file of cylinder0603.vtk is the file Paraview entered, test_cut.vtk and test_cut.stl are the files expored by Paraview.But SOFA can not read test_cut.vtk.
Can you help me see what’s wrong?

2.I want to creat a component of SOFA to select ROI.But I don’t know how to do because I am not the someone who specializes in learning software.
Do you have some examples of component for me to study?

Thanks,
Jake

Hello @Hugo,

During this time I have tried your method.But I have a problem.

The file of VTK saved by using Paraview cannot be read by SOFA.The waning messages are as follows:
[ERROR] [MeshVTKLoader(boxROI2)] ERROR: unsupported cell type 13
[ERROR] [MeshVTKLoader(boxROI2)] ERROR: unsupported cell type 13

The version of Paraview is 5.8.0.I have tried this methods:https://www.sofa-framework.org/community/doc/components/misc/vtkexport/. But those problems still arise.

Can you help me to sovle this problem?

Thanks,
Jake
