Extended XML import/export: Now includes meshing, setup, and export settings
The option to export and import TwinMesh project settings as an XML file has been extended. In addition to geometry settings the following project information are exported in the XML file:
– Assigning of the geometry
– Mesh settings (incl. node definition on curves)
– Definition of geometry points
– CFD setup settings
– Export settings
The time-consuming manual process of assigning geometry and setting the necessary parameters is no longer required for the following projects, as the chosen settings can be reused with only minor modifications. In new projects, you simply need to import the new geometry and then import the XML with the machine specific default values. This significantly streamlines the workflow and further reduces manual effort. Additionally, the XML file now serves as the foundation for full automation using the new batch processing capabilities. This allows all program settings to be applied automatically without using the GUI, further enabling efficient, script-based workflows.

Eccentric screw pump with variable pitch or co-rotating axis
It is now possible to define a table for the wrap angle, allowing you to specify a variable pitch and to use co-rotating directions for both the main and eccentric rotations.

Extended batch command list
The available command line arguments have been extended to include, for example, mesh generation and grid export, as well as several additional options. These batch commands are particularly useful for integrating TwinMesh into a fully automated workflow, enabling seamless transitions from geometry generation, through meshing, to CFD simulation and post-processing. Such a workflow facilitates easy changes to input parameters and supports efficient parametric studies.
Optimized “Accurate mapping” at interface
Quality is increased by using “accurate mapping” with a high element size ratio at the interface. Non-uniform node distribution along the interface is taken into account.

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.
