TwinMesh automatically generates high quality hexahedral grids for the moving parts of rotary positive displacement machines such as gear, lobe, gerotor and vane pumps or screw and scroll compressors.
TwinMesh is complementary to market leading CFD solvers like Simcenter STAR-CCM+ and Ansys CFD. It allows for reliable CFD analysis of pd machines using all physics available in these CFD software packages.
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 major CFD solvers.
Efficient
Structured grids made with TwinMesh allow for reasonable transient CFD model size while ensuring maximum numerical quality.

Screw compressors for green hydrogen at Aerzen: Demands and challenges
While development and simulation of screw compressors for heavy gases as air or refrigerants are quite usual, those for light gases, here especially hydrogen as future carrier of green energy, make high demands on internal clearance sizes, rotor profiles, and operating conditions to ensure high efficiency.
