Mathematical modeling of impeller-generated flows is highly used to simulate many industrial scenarios such as stirred tank bioreactor fluid dynamics. Despite their ability to mimic realistic problems and save experimental design costs, fluid-structure interaction simulations have drawbacks such as the mathematical complexity needed for its representation and the time required for large in silico experiments. Here we present a set of combined strategies for improving planning time consumption at those simulations, consisting in fluid-structure calculus and domain simplification in addition to the application of high performance computing. This solution implements a two-dimensional simplified actuator line model through an MPI-based parallelized code. This numerical study provides relevant information about how to efficiently implement a solution for problems with similar characteristics.
