Variable fluid convection thermal resistance in pipe objects #304
Description
This issue will implement teh possibility to supply an array of thermal resistances R_fp along with an array of fluid mass flow rates to handle the variation of delta-circuit thermal resistances with regards to fluid mass flow rates. The delta-circuit thermal resistances will then be pre-computed and interpolated during simulations. Interpolation could also apply to effective thermal resistances in Pipe and Network objects to speed up simulations.
