Running Nalu

This section describes the general process of setting up and executing Nalu, understanding the various input file options available to the user, and how to extract results and analyze them. For the simplest case, Nalu requires the user to provide a YAML input file with the options that control the run along with a computational mesh in Exodus-II format. More complex setups might require additional files:

• Trilinos MueLu preconditioner configuration in XML format

• ParaView Cataylst input file for in-situ visualizations

• Additional Exodus-II mesh files for solving different physics equation sets on different meshes, or for solution transfer to an input/output mesh.
