ASOFI3D stands for Anisotropic Seismic mOdeling with FInite differences in 3D. This code is intended for the modeling of seismic wave propagation and is based on SOFI3D code with the addition of orthorhombic anisotropy.

Obtaining the code

Get the code from this repo:

git clone [email protected]:swag-kaust/ASOFI3D.git

Then switch to the created directory:

cd ASOFI3D

Building the code

The prerequisites for ASOFI3D are:

• C compiler (for example, gcc), which supports C11 standard
• MPI library (for example, OpenMPI)
• GNU Make build system

Building the code with gcc and OpenMPI on Ubuntu

On recent Ubuntu versions such as 14.04, 16.04, or 18.04 all prerequisites can be obtained by the following commands:

sudo apt-get install gcc libopenmpi-dev make

Then while in the root directory of the code, build the code via command

make

which compiles the solver and several auxiliary utilities.

Before compilation, make will automatically test for the ability to compile MPI programs and generate file src/config-auto.mk with the flags for compilation.

Example usage

After successful compilation, you can run the code via command

./run_asofi3D.sh np dirname

where np is a number of MPI processes you want to use and dirname is the directory that contains configuration of the problem to solve. Parameter dirname is optional and defaults to par, so that the main configuration file of the solver is par/in_and_out/asofi3D.json.

Running the tests

To run the tests, Madagascar is an additional prerequisite. Tests are run via the command

make test
