ExaWind TIOGA utilities

This repository contains utilities to demonstrate overset connectivity within the ExaWind project using TIOGA between unstructured meshes in Exodus-II format using STK and block-structured meshes using AMReX

The code generates two executables:

• stk2tioga -- Standalone utility to test overset connectivity between unstructured meshes that are all in one Exodus file.

• exatioga -- Utility to test overset connectivity between multiple unstructured meshes (provided in Exodus-II format) with a single AMR background mesh with multiple levels of refinement.

Building from source

The following dependencies must be available on your system:

• TIOGA -- For use with AMR meshes, you should checkout the exawind branch of TIOGA.
• Trilinos
• AMReX

# Clone the git repository
git clone --recurse-submodules -b exawind [email protected]:sayerhs/tioga_utils.git

# In an already cloned repository
git fetch origin
git checkout --track origin/exawind
git submodule update --init --recursive

We recommend using exawind-builder to configure and build the dependencies as well as tioga-utils.
