I am looking for more information about the solver speed-up / performance improvements achieved in the SolidWorks Flow Simulation 2020 release. I'm specifically looking for data from further testing that was done and possibly a bit of how or where the performance has been improved on the same hardware. The time to solve has been significantly decreased for the same exact problem (model and setup) on the same hardware.

Here is some data (given in time in seconds to solve a set number of iterations) to compare the same conjugate heat transfer benchmark problem of about one million cells from 2019 to 2020 releases:

Intel i9-9900K [8 cores]
2019: 432 s
2020: 281 s

Intel Xeon W-3245 [16 cores]
2019: 319 s
2020: 228 s

I run this full blown (i.e. without symmetry) benchmark model with scStream till full convergence (variables variation = 1e-4) on a machine with Xeon e5-2630, 2.2GHz. It took only 47seconds. No initial conditions were assigned. I was using 8 of the available 10(20) cores. The results followed precisely the blue graph on Fig 13.4 (in the supplied pdf file).
