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 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 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 orthogonality and 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.
