MoorDyn initialization #163
Description
Dear OpenFAST team,
I have installed the latest release of openFAST 4.1.1, and I am testing my setup by running a surge decay test of the OC4-Semisub platform. The time to run a 600s simulation case is higher than what I used to run in v3.5.2. Is that normal or there is something wrong in my settings?
Moreover, I also get this error when running the case related to Moordyn. What could be the issue?
Regards,
Abdu
