Abstract
The presence of moving meshes when motions of fluids and solids are being simulated requires a good control of the cells topological deformations. The work done in getting the control of the mesh morphing techniques in Computational Fluid Dynamics (CFD) applications of fluid-structure interactions and rigid bodies motions is here presented. The effects of imposed rigid body motions on a fluid mesh surrounding a solid body are analysed and strategies for maintaining a reasonable quality mesh during its deformation are investigated and developed. Java programming is employed in order to automate the process of re-meshing when the mesh deformation is dangerously close to the degeneration.
