TwinMesh 2025 is advanced mesh generation software based on years of CFD simulation expertise, designed for computational fluid dynamics (CFD) simulation of the changing fluid volumes within the working chambers of rotary positive displacement (PD) machines. It automatically generates high-quality hexahedral meshes for the moving parts of rotary positive displacement machines (such as gear pumps, vane pumps, helical pumps, and screw or scroll compressors) through simple operations. It enables reliable CFD analysis of PD machines using all physical fields available in these CFD software packages. TwinMesh provides high-resolution and high-quality numerical meshes, avoiding interpolation errors, and enables the use of all physical fields available in major CFD solvers. The structured meshes created using TwinMesh allow for reasonable transient CFD model sizes while ensuring the highest numerical quality.
