STORM

STORM plasma simulation model, built using BOUT++ framework.

This is the public release version of STORM. The model assumes cold ions, but includes electron temperature evolution. The current development version, used at UKAEA/CCFE may have significant features added that are not yet included in this public release. If you are interested in using features that have not been released yet, please contact us to set up a collaboration.

This version of STORM has been tested with BOUT++ v4.4.2.

Quickstart

To compile STORM: 1. download and compile BOUT++. 2. Configure STORM to link to your copy of BOUT++. In this directory, run bash cmake . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=../build_bout This command assumes that you followed the BOUT++ instructions to build BOUT++ in a directory called build_bout, which is located one level up from this STORM directory. Otherwise modify the path passed to -DCMAKE_PREFIX_PATH. 3. Compile STORM bash cmake --build build

Test

To test STORM is working correctly, you can use an example 3d filament simulation. 1. Install the boutdata Python package (used to load output from the simulation) bash pip install --user boutdata You can also install boutdata using conda. 2. Run the test. For example on a machine with 8 cores bash cd tests3d ./test_filament_3d.py 8 The terminal output should report 8/8 tests passed in test-3d The test should take ~1 hour in serial (on a 3Ghz Intel Core i7 CPU), but also should scale well at least up to 48 cores.
