Strand7 Sparse Solver Release Beta 1

May 23, 2002

We are very pleased to announce this new release which offers significant increases in solution speed for all the Strand7 solvers.

During the past 18 months we have focused a great deal of effort into the development of this completely new solver for Strand7. As with the rest of the Strand7 development, the new solver has been developed entirely in-house from scratch and is fully integrated into the Strand7 environment.

The new solver is a Direct Sparse Solver. This means that it provides the same reliable result quality as the existing solver, but in a much shorter time. In other words, the new solver is not iterative so solver convergence is not an issue.

The following list presents a selection of comparative solver run-times for medium to large Strand7 models. All models were run on an PC with an AMD Athlon processor, running at 1.4GHz. The system had 1.5GB of installed RAM, but the important RAM measure is the amount actually used by the solver (as reported in each case below).

If you are interested in obtaining a copy of this new solver, please contact us to check your eligibility for a free update: support@strand7.com
