Looking for software for Unsteady BEM analysis, pls suggest

Hi all
i’m Ijaz from Singapore. I need to calculate the pressure distribution at differenet sections using BEM. Generally I have written BEM MATLAB code for steady analysis. But now I need to implement unsteady analysis. Can anyone suggest me a good opensource software for Unsteady BEM analysis.

Dear Ijaz,

By “BEM,” are you referring to a panel method for calculating loads on airfoils or the classic momentum approach used for calculating wind turbine rotor loads (using an actuator line representation of blades)? You referred to “pressure distribution”, so I’m assuming you are referring to the former, but I wasn’t sure. NREL doesn’t offer a tool for the former, but for the later, NREL’s AeroDyn module (which is coupled to FAST) applies.

Best regards,
