Overture

Abstract

The Overture class library can be used to easily write efficient programs in C++ to solve partial differential equations in complicated domains. Overture classes enscapsulate the details involved in discretizing PDEs in curvlinear domains letting the developer work at a higher level. Operator classes, for example, define differential operators using finite-difference and finite-volume discretizations. Overlapping grids are used to represent complicated geometries. Large difficult problems can be solved using adaptive mesh refinement and moving grids. The Overture library is based on the A++/P++ array class library which provides a portable path to creating solvers for parallel machines

TargetEnvironment

Supported platforms: Overture has been run on the following systems: Sun Solaris with Mesa (OpenGL); SGI with the IRIX??? or newer operating system (64 bit, and origin 2000) with native OpenGL; DEC alpha with Mesa; HP with Mesa ( HP-UX B.10.20, C++ HPCPLUSPLUS A.10.??); LINUX with the egcs compiler (an advanced version of gcc available free from http://www.cygnus.com/egcs) and red-hat motif (available for a small fee $100? from ???). The public domain version of Motif, Lesstiff (from http://www.hungry.com), does not currently work as the popup menus don't seem to appear.
