I have recently used Azure Batch to do CFD simulations using OpenFOAM®, and I summarize my experience and the procedure I followed below. Before entering the details, it is worth saying what Azure Batch is. Azure Batch is a compute management service that lets users to rapidly deploy batch processes either by running multiple tasks on individual nodes, or a single task on multiple nodes, with high-performance communication (Infiniband or, as it is called in the service, RDMA). While Azure Batch is not a full replacement for an HPC cluster with standard queue systems, it is a convenient option for projects that require a defined number of simulations that need…
