How to apply varying angular velocity to a model
Altair EmployeePlease someone tell me is it possible to apply varying angular velocity to a model in Optistruct. If not is there any other way to simulate a rotating component having varying angular velocity

Hi Shanky,
why not use MotionView/MotionSolve?

Hello
with a varying angular velocity, stress field of such component may not be static
So if you are doing dynamic analysis you can set variable angular velocity by rload1

@Prakash Pagadala. - Sorry sir I had used word simulation. Actually I want to do thermomechanical analysis. You might remember the model which you corrected having TABLED1 entries. I want to continue with that by applying varying pressure wrt time on pads in frictional contact with the rotor and varying angular velocity wrt time applied to disk. In addition to this I want to use the transient thermal analysis results to calculate thermal stresses and then see combined effect of the mechanical and thermal stresses. Currently I am not able to figure out what should I do. My queries are :
1. Whether I can use TLOAD1 for defining varying pressure also, as in TLOAD help it shows only force and moment.
2. If TLOAD1 can't be used what shall I use to define time varying pressure.
3. Can DLOAD be used in combination with RLOAD and TLOAD just by defining DLOAD_NUM =3 (which is the simple addition) and giving values S=1, S(1)=1, S(2)=1, S(3)=1.
4. If I cant do anything like above please suggest me any direction in which I can proceed.
@Tinh - Thanks for the reply. I will see to it and revert back to support forum

You can use TLOAD1 with type as VEL which should refer to a SPCD
