Tip! Refine or expand your search. Authors are sometimes listed as 'Smith, J. K.' instead of 'Smith, John' so it is useful to search for last names only. Note this is currently a simple phrase search.

[ascl:1106.022] MPI-Defrost: Extension of Defrost to MPI-based Cluster Environment

MPI-Defrost extends Frolov’s Defrost (ascl:1011.012) to an MPI-based cluster environment. This version has been restricted to a single field. Restoring two-field support should be straightforward, but will require some code changes. Some output options may also not be fully supported under MPI.

This code was produced to support our own work, and has been made available for the benefit of anyone interested in either oscillon simulations or an MPI capable version of Defrost, and it is provided on an "as-is" basis. Andrei Frolov is the primary developer of Defrost and we thank him for placing his work under the GPL (GNU Public License), and thus allowing us to distribute this modified version.

[ascl:2405.008] i-SPin: Multicomponent Schrodinger-Poisson systems with self-interactions

i-SPin simulates 3-component Schrodinger systems with and without gravity and with and without self-interactions while obeying SO(3) symmetry. The code allows the user to input desired parameters, along with initial conditions for the Schrodinger fields. Its three function modules then perform the main (drift-kick-drift) steps of the algorithm, track the fractional changes in total mass and spin in the system, and then plot results. The default plots are mass and spin density projections along with total mass and spin fractional changes.
