Hello Guys, How are you ?

I just graduated, so i started performing some analysis using FEMAP v10.3 besides that i was using SolidWorks Simulation to run my simulations.

Usually i model the part using solidworks and then import it to FEMAP. I am having problems to run this study, always getting the same error : " RUN TERMINATED DUE TO EXCESSIVE PIVOT RATIOS IN MATRIX KLL" i was aware that this error is due to the parts of the model are not connected or your model is not correctly constrained. To fix this you have to:

1- Change your fixtures.

2- Merge nodes.

3- Connect faces.

I tried all of this solutions but i did not get my problem solved. Could someone help me ?

Solved! Go to Solution.

Hello Karachun, thanks for replying !

I performed modal analysis, and changed the property as T_Giampietro said. This is the outcome:

NO EIGENVECTORS COMPUTED FOR COMPONENT MODE SYNTHESIS OR SYSTEM SOLUTION.

Range of interest: from 0 to 100.
