Tips & Tricks

Using HyperStudy with a remote HPC infraestructure via Altair Access.

Altair HyperStudy is a design exploration tool that manages simulation model variability, run submission and extracts simulation responses. HyperStudy allows to seamlessly perform Design of experiments, generate metamodels and perform optimizations and reliability studies. However, some simulations are computationally expensive to run in local machines. Altair Access can assist to submit the jobs to a remote HPC server seamlessly, with the reduced simulation time and increased compliance with IT policies.
