Abstract:

The paper presents an implementation of adaptive hybrid meshes in a FEM code designed for 3D simulations of flow in artificial heart chambers. Special emphasis is put on taking into account moving parts of artificial heart chambers, like valves. Toward this goal a weak formulation for problems with moving boundaries and algorithms for mesh modifications, including remeshing, are developed.
