I have successfully completed an openFOAM analysis of a vertical axis wind turbine consisting of three twisted Savonius blades (see pic below). The CFD analysis was used to primarily compute the moment generated by the wind at specified rotational speed of the turbine using arbitrary mesh interface (AMI). Now I want to use the data generated by CFD analysis to perform structural dynamic analysis of the turbine and look for instabilities during rotation. Specifically I want to run harmonic (steady state dynamic) analysis in a FEA program like ABAQUS where the turbine model has been assembled, discretized and meshed with structural elements. Please understand that I am not interested in performing a Fluid-Structure interaction analysis at this point, but strictly a structural dynamic analysis of the turbine with harmonic aerodynamic loads as input.

My questions are two-fold:

1. whats the best way to output the pressure load generated as part of the openFOAM analysis on specific patch points of one of the blades in the rotating coordinate frame (instead of the fixed inertial frame that has been performed already)?
2. how can I transfer the pressure load at different time steps to a computational structural mechanics software package like ABAQUS?

Do you still have the case file of this turbines?

Best,
