Title: Absurd Solving Times
Post by: jleachul on January 30, 2018, 09:50:03 pm
Hi All,

Background:
Trialling Pyrosim 2017 for model building and solving in FDS-SMV 6.6.0 with MPIEXEC, 20 meshes each dividing the domain equally but refined and assigned equally to mpi_process 0-3.

Regardless of how many cells are in the domain (2E+6 or 3E+5 and many in between) and regardless of the computing power (4, 8 or 16GB of RAM with high end processors) the solving time is circa 600 hours.

When working with previous companies in older versions of Pyrosim I have solved models of 3E+5 cells in 6 or so hours.

Should I be building the model in a previous version?

Any help would be greatly appreciated.

Thank you
