Hi everybody! I have a problem in applying boundry conditions on Automotive body (Body In White) to get the first bending and torsional natural frequencies.
As the following, are my questions:
1-What are the boundry conditions to get the first bending and torsional natural frequencies?
2-What method in ANSYS is better to get these frequencies?(i mean reduced or subspae method?)
I wish if someone can help me with or any tips to conduct this analysis.
Thanks for your help and time.
