Hello,
I have two PSD signals which I have to introduce to my model in two diferent directions simultaneously. I am not sure if this is possible and how to do it in case it is...
I was trying to do it by mean of a base motion (psd type=base). In the results I want to check the streess in each frequency increment of the step, not the RMS.
My step definition in the input (after the frequency step with the modes) for one direction is the following.
*STEP
*RANDOM RESPONSE
1,100,50,1,1
**
**
*MODAL DAMPING, MODAL=DIRECT, DEFINITION=FREQUENCY RANGE
1,0.05
100, 0.05
**
*CORRELATION, TYPE=UNCORRELATED, PSD=P1
1,1
**
*BASE MOTION, DOF=1, LOAD CAsE=1
**
Any help? Thak you in advance!
