Altair SimLab

Altair SimLab is a multidisciplinary simulation environment designed to help you automate the setup of complex engineering analyses. Instead of manually creating meshes for every part, you can use feature-based modeling to automatically recognize CAD geometry like holes, fillets, and ribs. This allows you to move from raw CAD data to a functional simulation model in minutes rather than hours, ensuring your engineering cycles keep pace with rapid design changes.

You can perform various analyses including structural, thermal, and fluid dynamics within a single interface. The platform is particularly effective for mid-to-large scale manufacturing companies in the automotive, aerospace, and electronics sectors. By capturing and automating repetitive modeling tasks, you reduce human error and free up your engineering team to focus on interpreting results and optimizing product performance.

CONVERGE CFD

CONVERGE CFD changes how you approach fluid dynamics by removing the most time-consuming part of the simulation process: manual meshing. Instead of spending days or weeks refining grids, you can rely on its autonomous meshing capabilities to create the mesh at runtime. This allows you to simulate complex moving geometries and intricate flow patterns with high accuracy and significantly reduced setup time.

You can apply this tool across various industries, from internal combustion engines and gas turbines to pump design and medical devices. The software excels at handling transient simulations where boundaries move or change shape, ensuring your mesh always adapts to the physics of the problem. By automating the grid generation, you can focus your energy on analyzing results and optimizing your designs rather than troubleshooting mesh quality.
