Hello everyone, 

 I have a model and I am trying to model it using acoustic modal analysis , I assigned everything correctly but when I came to solve the model an error message popped up " The Eigenproblem is ill-conditioned so the results accuracy may not besatisfactory. Modifying the initial value of the frequency shift(FREQB in the MODOPT command) may solve the problem. Eigensolveprocess is stopped.", would you please help me to solve this problem?

What did you request as your initial frequency?
