Random vibration analysis unit conversion in optistruct
As shown in the below image for converting units in SPCD for both mm/s2 and m/s2 the value is 1, i think it is 1 for mm/s2 and 1000 for m/s2; please correct me if i am wrong

Thank You Lacie
Hari,
You are correct-- if we are using a mm/s/ton/N unit system, but the input we have for PSD is in meters, we would either need to scale the PSD curve when we input into HyperMesh or scale the SPCD to make the units consistent.
