Abstract:Mesh moving scheme is an important issue in many fluid-structure interaction problems. In this paper a new mesh motion technique is presented for the effective treatment of moving mesh. The entire deformation is imposed at each time step and the motion of the internal nodes is governed by a modified Laplace equation. Finite element method is adopted to solve the Laplace equation with elemental Jacobian-based stiffening technique. Nodal coordinates are updated by using the total nodal displacements and initial … Show more
