The On Ramp/Level 1/Solve (Compressible)

This guide is for running compressible PHASTA simulations. If you are working on an incompressible simulation, please see Level 1 Solve.

Overview

This page walks you through the process of configuring, compiling, and identifying the correct executable for running compressible PHASTA simulations. These steps assume you have generated and partitioned a mesh using Prepping the Grid for Chef and The On Ramp/Level 1/Partition.

Building PHASTA for Compressible Simulations

Use the following script to configure and compile PHASTA with compressible physics enabled. This ensures that both compressible and incompressible functionalities are available.

#!/bin/bash

Target=Example_Build
mkdir Example_Build
rm -r $Target/*
cd $Target

export PKG_CONFIG_PATH=/users/skinnerr/tools/git-petsc/build_ompi210_gnu63/lib/pkgconfig/

cmake \
-DCMAKE_C_COMPILER=gcc \
-DCMAKE_CXX_COMPILER=g++ \
-DCMAKE_Fortran_COMPILER=gfortran \
-DCMAKE_BUILD_TYPE=Debug \

After compilation, confirm that the compressible PHASTA executable has been built:
