**Frequency Response Analysis :**

In Unigraphics (UG NX) Advanced simulation FEA, we can simulate Frequency Response Simulation based on modal analysis results.

The steps for performing a Frequency response simulation are as follows :

- Prepare FEA model with Proper material, Boundary conditions etc
- For restraints use Fixed restrain and Apply Enforced motion location at the desired points or nodes
- For Solution type: Choose SEMFREQ 111
- Subcase to solve : Modal Frequency
- After solving for the solution set, now we have to create a response simulation .
- Right click on the part.sim , Go to New Solution Process: Response Simulation
- Right click and create New Evento Go to Event manager in Tools to create New Event
- Function Tools: To create a frequency function of type General- Spectrum
- Now for an event, select the enforced motion and for that enforced motion apply the function you have created.
- After creating a Frequency event, now Right click and choose Evaluate Contour results - Response
- Choose the desired output you need to obtain and select all the elements of the modal.
