Leeds Dynamo simulations for accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos

This dataset contains numerical simulations of spherical shell magnetohydrodynamic simulations at parameter regimes designed to encourage magnetic field polarity reversals. Each folder contains the code and starting point required to reproduce a single simulation. The files present are 1. state.cdf.in - the checkpoint file used to initialise the simulation. 2. main.out - the executable simulation code, set up for the specific parameters for each simulation. 3. main.info - details of parameters for each simulation - can be used as a reference for recompiling the code to re run the simulation. 4. run.bolt - the submission script for the ARCHER2 HPC which was used to start each simulation. A selection of time averaged quantities can be found in "Andrew T Clarke, Christopher J Davies, Stephen J Mason, Souvik Naskar, Accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos, Geophysical Journal International, Volume 246, Issue 1, July 2026, ggag092".
