International TwinMesh Users’ Summit

The International TwinMesh Users’ Summit is an event planned for both, existing TwinMesh users and engineers interested in reliable CFD simulation for rotary positive displacement (PD) machines. TwinMesh is a grid generator complementary to ANSYS CFD which automatically generates high quality hexahedral grids for the moving parts of rotary PD machines such as gear and gerotor pumps, screw and scroll compressors, as well as lobe pumps. Combined with ANSYS CFD the TwinMesh approach allows for very efficient and reliable CFD analysis of such machines and helps engineers to understand and improve their designs.

The full presentations are not available for this workshop.
