   when we give acceleration in spcd and tabrnd1 while during random vibration analysis will the accelerations add up or multiply?

 

 

Thanks,

    Can you explain your question?

    The SPCD value is a multiplication factor to the table entities.

    hi, 

    when i give spcd =1 and one of the tabrnd1 values as 0.002 then a whole acceleration  acting on the node will become 0.002 or 1.002?
