Load modal analisys results in dynamic analisys

Hello everyone.

Basically, i have a big model with lots of elements, in which the modal analisys takes quiet too long to complete.

In this model, i need to perform some tests using time history/dynamic analisys using nodal superposition, but everytime i run a time history analisys, a modal analisys is also performed.

 

But the geometry is all the same, i am only viring some curve parameters, i don't need to run a modal analisys everytime i want to change some curve parameters.

 

I want to know if it's possible, within FEMAP, to load the modal analisys inside the dynamic. In order to save some time.

 

Best regards,

Igor Carvalho

Yes, this is called Restart. Check Example 16. Modal Frequency Analysis of the Hinge Model in Help -> Examples.

Thanks, that worked.

Even though now i realized that what actually takes time is not the modal analisys, but rather the ammount of reults requested.

 

Anyway, thanks for your time.
