I have never worked with 3D Slicer before and I am quiet new in this field. But I would like create a 3D model out of CT-DICOM-data. It is important that the HU values of the cortical and trabecular bone will be safed in the output (as .igs) for further Finite element analysis in ABAQUS or FEBio. F…

Thanks a lot for your help! I tried to safe the file as .vtk but still cannot load it into FEBio. I can only load the .stl file as binary format. Hence I wrote FEBio, if there is any other possibilitie. I will keep you updated. Do you know if ABAQUS is better in this case?

I’ve just talked to the developer of FEBio Studio about this and he fixed unstructured grid import from ASCII VTK files today. I don’t know when he will update the FEBio download page, so ask him on the FEBio forum or at the contact email address.

Thank you so much for your efforts! I tried to safe another 3D model in .vtk but it is showing me this error: "Cannot write data file: C:/Users/Admin/Documents/Jeffs-Data/Test/5. Trial_ Threshold_300-1800 L5/23052020_L5/LabelMapVolume.vtk. Do you want to continue saving? Do you know what is the p…

Likely a permission issue. Try to save to a folder where you have right permission.

Also make sure you don’t have any special characters in any of the folder or file names. You might find some more details in the application log.

[vertebral model] I would like to create a volumetric model of this vertebra. I tried to mesh it with the segment mesher module in order to export it as .vtk file and the result looks like that: [meshed model] What am I doing wrong?

How to biomechanical analysis of the vertebra: solidify the bone using “Wrap solidify” effect (provided by SurfaceWrapSolidify extension ) generate a volumetric mesh using SegmentMesher extension save generated volumetric mesh with “Compress” option disabled into .vtk file load .vtk file into FeBIO…

Dear Mr. Lasso thank you for your reply! Unfortunately today the extension database did not work, so I could not try the SurfaceWrapSolidify extension yet But I am also not sure if this solidifying module can lead to the model I need, cause I think for a precise FE analysis I need to model the can…

Unfortunately today the extension database did not work Every day the Slicer Preview Release shows up around 1am EST but extension builds are completed around 10am EST, so depending on your timezone, you may not see extensions for a while. You can retry installing extensions now or install yester…

Thanks a lot for your reply! I tried the Wrap Solidify Module, but this is the best I could get out of it. There are still holes and even peaks on the surface. What am I doing wrong with the setup? [wrap solidify.PNG] [image] lassoan: Therefore, you need to fill in these “holes” in the segme…

Is it possible to do a segmentation of the lumbar spine from CT-data and use the 3D model (.igs) for further finite element analysis in ABAQUS or FEBio?
