HAD is a computational toolkit providing distributed adaptive mesh
refinement for partial differential equations.
It provides a flexible environment for diverse applications which can
be combined or employed individually.
To date we have implemented applications for the Einstein equations;
General Relativistic Magneto Hydrodynamics and (complex) Klein-Gordon
fields. These have been employed in full 3D simulations of:
Single and binary black holes; critical phenomena. (Einstein
equations in vacuum)
boson stars, critical phenomena, and cosmological scenarios. (Einstein
equations coupled to complex scalar fields)
Single and binary polytropes, accretion disks. (Einstein
equations with a matter source )
Impact of magnetic fields on single and binary stars. (Einstein
equations coupled to a matter source and magnetic fields)
Dynamics of single stars. (General relativistic hydrodynamics in
the Cowling approximation)
In these pages you will find links to presentations, publications and
research specific pages with further information about our research
activities. Also you can download HAD here.
