Abaqus analysis of Knee Joint
Abaqus analysis of Knee Joint
(OP)
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.

2. Has the analysis terminated after 100 increments? Then look at the step definition and increase this upper limit.
RE: Abaqus analysis of Knee Joint
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?
