Hi,

I am making topology optimization for my bachelor thesis. I have a simple rotating disk which rotates at 4500 RPM. I want to make static analysis. When I apply RPM I always have the same error. Can anyone help me please. I uploaded my disk in attachment

Thank you in advance

Hi, 

You did not supply value for 'A' field in RFORCE card

actually you should set A=4500, and let vector R1R2R3 in normal form (0 0 1)
