I already made quite some computations with the IEA-15-240-RWT model with the ElastoDyn blade model, but did not succeed so far in using the BeamDyn blade model instead.

I was wondering what other changes are required (other than changing the switch and reducing the time step) to successfully run the BeamDyn model.

The error I receive is :
