How do I calculate the natural frequency of this acid tank


Hello all

I recently work in a freelancer web and have done some designing for employers.

One of them has sent the picture and profiles of an acid tank and requested me to calculate its "Natural vibration frequency" with Catia. I designed the tank with three internal separators sheet.

But my task is not complete and I must calculate its " natural frequency out of a truck.

Well, I'm familiar with Analysis section of Catia respectively, but have never worked with frequency workbench before. I kn ow how to invert the tank into mesh and how to clamp its body but don't know which instance use for calculating the " natural vibration frequency" of the tank.

The employer is asking me to do that for him in a short time.

please tell me which instances I should to use for calculating the natural frequency of the tank

Thank you beforehand
