Rotational velocity

Altair Forum User · July 2019

Hi,

I want to simulate a fan rotation problem in radioss. I want the fan to be rotate in a particular rpm.

As I know with imposed displacement with XX,YY or ZZ direction we can input it. But where to set the rpm as per requirement.

Is there any options to define the rpm.

kindly suggest.

Hi,

the function can be constant or ramped up to the rad/s value calculated from RPM.

Hi Simon,

i cannot open the "rpm_0000.rad" which you shared. can you please upload a new one?

Thank you

the value input for rotational velocity is in rad/s, if your value is in rpm, you need to multiply by 0.104719755 (1 rpm in rad/s)
