Fast – Reliable – Efficient

A revolutionary meshing solution for reliable CFD analysis of rotary positive displacement machines

TwinMesh automatically generates high quality hexahedral grids for the moving parts of rotary positive displacement machines.

TwinMesh is complementary to ANSYS CFD. It allows for reliable CFD analysis of pd machines using all physics available in this leading CFD software package.



TwinMesh provides an automated workflow for structured mesh generation and CFD analysis setup of rotary positive displacement machines.



TwinMesh delivers high resolution and high quality numerical grids, avoids interpolation errors and allows the usage of the full range of physics available in ANSYS CFD.



Structured grids made with TwinMesh allow for reasonable transient CFD model size while ensuring maximum numerical quality.
