vortex-p code

Implements Helmholtz-Hodge decomposition for particle-based, moving-mesh or meshless simulations

Developed by David Vallés-Pérez

In collaboration with Klaus Dolag, Susana Planelles, Vicent Quilis, Frederick Groth, and Tirso Marín-Gilabert

This project has been mainly developed at the Universitäts-Sternwarte München and the Departament d'Astronomia i Astrofísica of the Universitat de València. The original vortex code was developed at the Departament d'Astronomia i Astrofísica of the Universitat de València, in the Computational Cosmology group.

This project has been supported by the Agencia Estatal de Investigación Española (AEI; grant PID2022-138855NB-C33), by the Ministerio de Ciencia e Innovación (MCIN) within the Plan de Recuperación, Transformación y Resiliencia del Gobierno de España through the project ASFAE/2022/001, with funding from European Union NextGenerationEU (PRTR-C17.I1), and by the Generalitat Valenciana (grant CIPROM/2022/49).
