Direct coupling of Euler flow equations with plate finite element structures

A procedure to compute aeroelasticity by directly coupling the Euler equations for fluids and with plate finite element equations for structures is presented. The coupled equations are solved using a time integration method. The accuracy is maintained using moving grids that conform to aeroelastically deformed shape computed every time step. The aeordynamic forces are transferred to structures by using simple lumped load approach and also a more accurate virtual surface approach
