Why there is formation of edges during the conversion of volumetric mesh of knee joint parts to initial geometry in ANSYS FE MODELER ?

01 January 1970 0 7K Report

I have performed 3D reconstruction of knee joint from MRI using MIMICS software and generation of Volumetric mesh using 3 matic software. The cdb files from 3 matic were later imported into Ansys FE Modeler to create the initial geometry .

Now, the problem that I am facing is that the model obtained in FE Modeler is very rough with lot of edge formation, though the models done in MIMICS software are smooth and accurate.

It has been observed from the FEA results that there are stress singularities at the regions of the knee joint corresponding to the location of the edges formed during the conversion process in FE Modeler.
