TwinMesh
TwinMesh is a meshing software developed by CFX Berlin Software GmbH, Germany. It automatically generates hexahedral meshes for the continuously changing fluid volumes of the working chambers of rotary positive displacement machines. The product was released in 2014.
The current product release is Version 2015 (v1.5.1.10), released in December 2014.
Mesh Types
TwinMesh can generate structured hexahedral meshes.
Meshing Techniques
TwinMesh's mesh generation employs the following meshing techniques and smoothing algorithms.
- Option to fix the nodes along the rotors, which results in a general interface between the rotor meshes.
- Option to fix the nodes along the housing geometry to get an 1:1 interface between the rotor meshes.
- Option to fix the nodes on one of the rotors so that the nodes on the other rotor are able to move. This method also results in an 1:1 rotor interface.
- Various smoothing algorithms to control mesh orthogonality and node equidistance in all three dimensions.
- Mesh quality check such as: determinant, min. angle, volume change, aspect ratio.
Geometry Support
TwinMesh supports IGES (.iges) and point data (.csv).
The following geometry modifications are available in TwinMesh.
- Rotor scaling
- Rotor translation
- Rotation angle offset
CFD Solver Interfaces
TwinMesh has built-in support for ANSYS CFX.
Supported Platforms
TwinMesh supports 64-bit Windows versions.
