Abstract

Strong coupling with a CFD software is usually suited to the coupled transient simulation of an hydraulic component (like a valve; a pump; ...) with its surrounding environment. Due to the nature of the solvers used by CFD code; co-simulation is generally the best way to couple a Modelica system-level simulator and a CFD solver. This article describes a methodology and the associated technology for establishing a cosimulation between a Modelica model simulated with an ODE/DAE solver like the one encountered in LMS Imagine.Lab AMESim; and a 3D model of flow computed by a CFD software. The physical; numerical; and computer-related aspects of co-simulation handled by this methodology are exemplified on an application test case in fluid power.
