Hi Shenal, That explains a lot, thank you! When I look into the link you send, it is stated that the linkage is a result of the kinematic chain equation. But if I look into this kinematic chain equation, it would seem that a force in one cylindrical joint could induce a translation in another. Is th...

Hi Shenal, If i understand the FeBio theory manual correctly, the force is applied to the origin, but translation is only possible along the z-axis, thus the location has no influence anymore since no valgus torque will result from this compression. Is this correct? The reason I ask this is because ...

Hi Shenal, Thanks for your kind reply, this helps a lot! So if you apply the force through the cylindrical joint, at what point is the force applied? At the origin of the cylindrical joint? Because if this would be the case, the location of the origin could lead to a moment as a result of this compr...

Dear all, I am working with the oks models for my Master Thesis project, and am applying a gait cycle through the rigid connectors. Imagionary rigid bodies are created to create the Rigid connector, a rigid cylindrical joint, with which two of the 6 Degrees of Freedom can be described. Now I have th...

Dear Ahmet Erdemir, I did try that, however, in 2.5 files 'fiber' is seen as a synonym for 'mat_axis'. In 3.0 files this is no longer the case. When loading it into FEBio Studio (3.0 files) it shifts into the MRTI part. I also tried to include this axes after loading the 2.5 file with the fiber outs...

Hi dr Schwartz, Thank you for your quick reply. The fiber stretch was included inside the output as <var type="fiber stretch"/>. I thought this should be the way to request the fiber stretch in the output, but it didn't give any results. It seems like the PreStrain isn't applied to the fibers. Kind ...

Hi dr.Schwartz, Thank you very much for your quick reply! FEBio Studio didn't read the bulk and density properly, but this has been solved and I got a new software version. I manually applied the PreStrain, however, I experience some problems. When looking at the Lagrange Strain it seems like the st...

Dear dr. Schwartz, Yidan, I am trying to apply prestrain on the tf_joint_v2p7 model as well, using FEBioStudio. I want to define it as a single value for the entire ligament. FEBio Studio seems a bit different in assigning material properties and applying prestrain. You gave an example for using the...
