Hi there,

I got this error when running a linear dynamic study : "Additional points are required in definition of the exciting curve, to cover the lower part of frequency range."

Any idea about what I am supposed to do to fix that ?

Sounds like Harmonic Analysis. And your input load sounds like its defined as a curve. The number of points on the curve must start and end with the same limitof frequencies you've chosen to solve for. RMC the study and go in to the Properties. Frist make sure you're solving for enough frequencies then select the Harmonic Options tab. There you will find the lower and upper limit frequencies. If you're varying between, say, 0 - 1000Hz then your input curve for your applied load or excitation must also have points defined in that range.
