Abaqus analysis of Knee Joint

[Vansh Mahajan]

I am currently working on Compressive stress analysis (static general) of Human Knee Joint on Abaqus. The assembly was modeled on MIMICS-19 and meshed (Tet-4 type) on 3-Matic software. On giving frictionless contact and standard load conditions, I am getting the following errors:
1. Volume of 3 elements is zero/negative.
2. Too many increments made in this step.

Kindly provide a solution.

1. In postprocessing visualize the 3 elements through the display group options and check how you can avoid those elements.
2. Has the analysis terminated after 100 increments? Then look at the step definition and increase this upper limit.

These issues are typical with image-based modeling.

a) You will need to clean up those elements, for instance, by moving their nodes.
b) Odds are there is a modeling mistake. What warning/error messages do you see in the .dat/.msg files?
