wecopttool.change_bem_convention

change_bem_convention(bem_data)

Change the convention from $-i\omega t$ to $+i\omega t$.

Change the linear hydrodynamic coefficients from the Capytaine convention ($x(t)=X{e}^{-i\omega t}$), where $X$ is the frequency-domain response, to the more standard convention used in WecOptTool ($x(t)=X{e}^{+i\omega t}$).

NOTE: This might change in Capytaine in the future.

Parameters:

bem_data (Dataset) – Linear hydrodynamic coefficients for the WEC.

Return type:
