We are pleased to announce the release of TwinMesh 2026! You can download the latest version in our user portal. Here we have some information about the new features for you:
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.
New post-smoothing type TM2026
This is an optimized method to increase the mesh quality for rotors where the rotor curve loop has sharp edges (highly twisted rotors, e.g., for vacuum pumps). It reduces instabilities when using non-default mesh settings. High mesh quality is crucial for reliable CFD calculations, as poor mesh quality can lead to numerical errors, convergence issues, and inaccurate simulation results. By improving the mesh in these critical regions, the robustness and accuracy of the CFD analysis are significantly enhanced, ensuring that simulation outcomes are both meaningful and trustworthy.
Import mesh including boundary and volume names
For Simcenter STAR-CCM+ mesh files (.ccm) and Ansys Fluent mesh files (.msh), the import function reads the available names of the boundary patches and volumes. These names are then available in the stator mesh component selection list. This allows you to select the names for the setup definition without having to add them manually to the list.
