Hello

I want to analysis structural dynamics analysis for IEA 15 MW RWT monopile model using BeamDyn instead of ElastoDyn. So, I change the relevant parameters, but the several errors are occurred.

Unfortunately your time step is still too large. I generally run with DT=0.0004 s We are well aware of the excessive computational costs, and we are waiting for a much needed improvement that will come in a few months with the release of OpenFAST v5.0

Thanks for your response

Moreover, Additionally, I think a ROSCO error occurred as shown in the figure below. But, this does not occur when analyzing the NREL 5 MW.

I believe those are simple warnings from ROSCO
