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.

Fast

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

Reliable

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.

Efficient

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

Works Seamless with ANSYS

Direct Export to ANSYS CFX

TwinMesh is fully optimized for CFD analysis using leading ANSYS CFD software. It exports mesh data in ANSYS CFX format and ready-to-run input files for ANSYS CFX.  

Built on Years of ANSYS Expertise

TwinMesh is developed by CFD experts from CFX Berlin Software GmbH, a certified ANSYS Channel Partner from Germany for almost twenty years now.

 Easy Import

In TwinMesh the import of rotor and casing contours is realised as a 2D cross section via IGES format or CSV text files. Casing curves can also be generated in TwinMesh. All these contours can be easily scaled in order to modify e.g. clearance dimensions between rotors and casing. Rotor positions can also be adapted after the import defining axis-positions for the directions X and Y. If required, TwinMesh then automatically generates interfaces between the rotor meshes.

 

Auto Generation of Hexahedral Meshes

In the next step TwinMesh generates hexahedral meshes for all user defined rotation angles. Using special smoothing algorithms the software takes care of a sufficient gap resolution, smooth changes between small gaps and larger chambers and an homogeneous element distribution.

 

Easy Export

 

After a final check of the numerical quality the grids can be exported as 3D model or as 2D model. The export data of TwinMesh contains all required meshes for a transient flow simulation as well as the required routines for the automatic mesh import while running the simulation in ANSYS CFX. Also, a ready-to-run simulation template is exported by TwinMesh, which enables an immediate start of a flow analysis with ANSYS CFX. Using the structured grids from TwinMesh singlephase and multiphase CFD and CHT simulations can be performed in ANSYS CFX.
