Random Vibration


Updated by Altair Forum User
How to resolve this error.. I am using HyperMesh/Optistruct?
Messages for the job:
*** ERROR # 2813 ***
TABRND1 referenced by RANDPS data returned a negative value for each
frequency. This is probably due to extrapolation of the TABRND1 data.
No results can be calculated.
*** PROGRAM STOPPED: FATAL ERROR(s) ENCOUNTERED.

TABRND1 freq range should be bigger than the freq1 card range.
Hi,
Can you please check the data provided in TABRND1 card?
If possible post the image of the table here.
