Foil 22 Application Motivation IV: Numerical Relativity (Contd.)

From Introduction to Computational Science CPS615 Computational Science Class -- Spring Semester 2000. by Geoffrey C. Fox


1 Fortran90 (array syntax) very attractive to handle equations which are naturally written in Tensor (multi-dimensional) form
2 12 independent field values defined on a mesh with black holes excised -- non trivial dynamic irregularity as holes rotate and spiral into each other in interesting domain
3 Irregular dynamic mesh is not so natural in (parallel) Fortran 90 and one needs technology (including distributed data structures like DAGH) to support adaptive finite difference codes.
4 Separate Holes are simulated till Merger
5 0.7
6 6.9
7 13.2
