FAQPage Schema
How do I run MPI parallelized CFD simulations using FluidSim for 2D and 3D Navier-Stokes equations?▼

FluidSim CFD simulations can be run with MPI parallelization by automating solver configuration, execution, and parameter management for 2D/3D Navier-Stokes problems. This streamlines large-scale pseudospectral solver orchestration and output handling.

What is the best way to set up a parametric study for stratified and shallow-water CFD solvers?▼

A parametric study for stratified and shallow-water CFD solvers is configured through automated parameter management and solver selection. This handles robust configuration, run orchestration, and comprehensive output extraction for varied fluid dynamics scenarios.

Can I use this approach for high-performance computing workflows requiring HPC safety checks?▼

Yes, this approach suits high-performance computing workflows by providing HPC safety checks alongside MPI parallelization. It ensures robust run orchestration and output handling for large-scale fluid dynamics experiments on HPC systems.

How does post-processing work after running pseudospectral CFD simulations with FluidSim?▼

Post-processing of pseudospectral CFD simulations involves built-in plotting, data extraction, and visualization tool compatibility. It handles comprehensive output including fields, spectra, means, and budgets generated from the FluidSim execution.

Does this CFD workflow support shallow-water and stratified Navier-Stokes solvers?▼

Yes, this CFD workflow supports shallow-water and stratified Navier-Stokes solvers. The solver suite includes ns2d, ns3d, stratified ns2d/ns3d, and shallow-water solutions for diverse fluid dynamics experimentation and engineering analysis.
