Overview
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.
Diabatix ColdStream
ColdStream is a cloud-native platform that transforms how you approach thermal management and cooling challenges. Instead of manually iterating through designs, you define your boundary conditions and let the generative design engine create optimized cooling structures for you. It handles everything from liquid cooling and heat sinks to complex battery thermal management systems, ensuring your components stay within safe temperature limits while minimizing pressure drop and material use.
You can move from initial concept to a high-fidelity, manufacturable design in a fraction of the time required by traditional CFD methods. The platform is built for engineers in industries like automotive, aerospace, and electronics who need to solve extreme heat dissipation problems. By moving your thermal simulation to the cloud, you eliminate the need for expensive local hardware while gaining access to powerful optimization algorithms that explore design possibilities you might never have considered manually.
