Hi guys,

For my research I'm performing a FEA on the knee joint. When solving I get the User Fatal Message 9317

I have looked up what may cause this fatal. The reason is the difference in stiffness of the parts of a human knee. I checked it by using the same material for every part. This way I don't get any fatal. I have seen on the internet that increasing the MAXRATIO will prevent this fatal.
Problem is: I can't find how I can change the MAXRATIO. Anybody can help me out? Currently using Siemens NX 10, Nastran SOL101.

Thanks,
Niels
