Overview

EPMDynamoCode is a simulation framework for convection and dynamos in a full sphere using a fully spetral method. For details of the nuemrical scheme, please refer to the paper

• Marti, P., & Jackson, A. (2016). A fully spectral methodology for magnetohydrodynamic calculations in a whole sphere. Journal of Computational Physics, 305, 403–422. https://doi.org/10.1016/J.JCP.2015.10.056

Key Features

• Dynamo and precession dynamo simulations

• Parallel computation support

• Spectral methods implementation

• HDF5 state file output

• Visualization tools for ParaView/Visit

Requirements

• Git

• GCC

• FFTW3

• LAPACK

• HDF5 (with parallel IO for MPI)

• CMake

Installation

Clone the repository:

git clone git@github.com:QuICC/EPMDynamoCode.git
cd EPMDynamoCode
git submodule init
git submodule update

Create a build directory and configure with CMake:

mkdir build && cd build
ccmake ../EPMDynamoCode

Configure the build options as needed.

Compile the desired simulation:

make DynamoSimulation -j4  # Example for dynamo simulation with 4 cores

Running Simulations

Basic Requirements

• parameters.cfg configuration file

• Initial state file (state_initial.hdf5)

• Simulation binary (e.g., DynamoSimulation)

Example Commands

# For dynamo simulation
./DynamoSimulation

# For precession dynamo simulation
./PrecessionDynamoSimulation

Documentation

• Technical documentation can be generated with make CodeDoc

• Configuration examples in Config/ directory

Note

The code has been upgraded to the QuICC code https://github.com/QuICC/QuICC-Solver. This repository is not supported and updated anymore.
