ARTSS

Accelerator-based Real Time Smoke Simulator

ARTSS is a real-time and prognosis capable CFD code basis simulating buoyancy-driven turbulent smoke spread based on finite differences and a large eddy simulation turbulence model. The open source code is portable on CPU and GPU and successfully verified using analytical and semi-analytical tests. It is also successfully validated with scenarios relevant for fire protection. ARTSS is based on JuROr, which was originally developed within the ORPHEUS project (funded by BMBF) by Dr. Anne Küsters.

Getting Started

Requirements

The serial CPU version of ARTSS can be compiled on Linux or MacOS systems with very few tools, whereas the multicore and GPU version needs an OpenACC capable compiler. Detailed requirements are listed in the table below (general requirements for serial version, specific for multicore and GPU version).

	Purpose	Tool	Version
General	Version control system (optional)	git	>= 2.0
	Build processor using a compiler-independent method	CMake	>= 2.8
	Compiler fully supporting C++-17 (gcc or clang)	gcc	>= 7.0
	Visualization of output	vtk	>= 5.8
	Testing for consistency of output while developing	Python	>= 3.6
Libraries	Logging	spdlog
	String formatting in output	fmt
Specific	Compiler fully supporting C++-17 and OpenACC	NVHPC	>= 20.9.0

Compiling the Code

Once the code has been checked out and all required software has been installed, ARTSS can be built from the terminal by first running cmake to configure the build, then running make. The steps are summarized below.

1. Clone

git clone --recurse-submodules https://github.com/FireDynamics/ARTSS.git
cd ARTSS

if you already have a local copy of ARTSS and are missing spdlog or fmt do a recursive submodule init.

git submodule update --init --recursive

2. Compiling the code

./compile.sh [OPTIONS]

Note: Without options all executables will be compiled using the NVHPC compiler and CUDA 10.1.

OPTIONS (selection; show all by using --help flag):

• '-s' -> Compile serial ARTSS version
• '-m' -> Compile multicore ARTSS version
• '-g' -> Compile GPU ARTSS version
• '--jobs [tasks]' -> Specifies the number of tasks to run simultaneously (default $(nproc))
• '--gcc' Use GCC as compiler

EXAMPLE:

• Compile serial version of ARTSS using 4 cores and GCC ./compile.sh -s --jobs 4 --gcc
• Compile multicore version of ARTSS ./compile.sh -m

Extra: It is also possible to work with ARTSS by using Docker. Instructions and further information can be found in DOCKER.md.
