Abstract

Efficient numerical methods are necessary to simulate the interaction of aerodynamic loading, heat transfer, and structural deformation. This paper presents a partitioned approach using seperate single field solvers for fluid and thermoelastic problems coupled by the third software package. The methods implemented in the used modules are described. On the way towards an aerothermoelastic solver, a stepwise validation is required. Here, the successful validation of the thermoelastic and aeroelastic solver is shown.
