Eigenvalue problem in Abaqus

ntuecd's picture


i am doing a eigenvalue test for a car body by using Abaqus. The computation runs successfully, but the 7, 8, 9, and 10 th mode are very small ( 1.264 * 10^-4). This means the model of the car body contains some loose parts.


I wanted to know if there is any way to find in Abaqus, which part of the body is loose.


Thanks for your help.
