Hello erverybody,
my name is Julie and i´m working on the knee in order to compare a knee with a pathological one.
In order to do this i need to convert the file .feb of the knee to a file .inp to work on Abaqus.
When i load the febio file with Preview I export un vtk file. This part is ok.
But when i want to save this vtk file on a inp file with the software GMSH, the cartilage and the ligament are missing and i have the error message: "unknown type of mesh element with 8 nodes" and finaly have the model but only the bone.
If someone can help me...
Thank you,
Cheers,
Julie

Re: Problem for Abaqus Conversion
Dear Julie,
Your best bet is to get the mesh in a format, e.g. inp, that Abaqus can load and redefine other model parameters in Abaqus. The way you describe may work, once you figure out why it is not necessarily able to import/export the element type. Yet, there are more convenient ways. Open Knee(s) - Generation 1- g1-s1-v1.0.1.202 (previous release you can get from the download section) has the mesh in Abaqus .inp format. I should note that te coordinate system of this mesh is different than what is used in the FEBio model but it may still work for your application. I will also advise you to check the dissemination by CalPoly folks - https://simtk.org/home/cphmbkneefem. They used Open Knee(s) - Generation 1 data to build an Abaqus model.
Best,
Ahmet
