% Causality for FP component

%SUMMARY FP: converts thermal pseudobond to true bond and vv
%DESCRIPTION Port [e]: temperature (T) / enthalpy flow (E) bond
%DESCRIPTION Port [s]: temperature (T) / entropy flow (S) bond
%SUMMARY FP: converts true bond to a pseudo bond with power flow as flow
%DESCRIPTION Port [f]: True bond with a flow covariable
%DESCRIPTION Port [p]: Pseudo bond with power (ef) as flow variable
