Set blade initial conditions for BeamDyn

Dear all,

Does anyone know how to set the initial blade tip displacement and initial pitch in BeamDyn? I know these values can be set in ElastoDyn input file. But I want to use BeamDyn to calculate the blades’ deformation. It seems that BeamDyn ignores these settings in the ElastoDyn input file.

I would really appreciate if you can help.

Best regards.

Dear Xiaoqi Qu,

It is not possible without modification of the source code to set an initial blade-tip displacement in BeamDyn. Instead, it is common practice to neglect the simulation start-up transient (typically about 30 seconds) before processing the output.

The initial blade-pitch angle is set within the ElastoDyn primary input file and applies to blades both modeled in ElastoDyn and BeamDyn.

Best regards,

Dear Jason,

Thank you for your kind reply. It is really helpful for me.

Best regards.
