Cactus

Cactus is a general, modular, parallel environment for solving systems of partial differential equations. The code has been developed over many years by a large international collaboration of numerical relativity and computational science research groups and can be used to provide a portable platform for solving any system of partial differential equations.

        Release Notes: The boundary and symmetry interfaces have been reworked to make the distinction between physical boundary conditions and boundaries conditions from mesh symmetries clear. The support for external packages has been enhanced by adding new configuration possibility for modules to state an explicit dependency on a library containing a particular capability to be present. There are many bugfixes and minor feature enhancements.
