Unable to use SMP for DEM simulation

I recently bought an Alienware desktop with Windows OS. I installed MFix on it.
I am unable to give a run for a DEM simulation with SMP. It is working for TFM though.

It starts the simulation and abruptly ends with:
MFiX process has stopped
Previous MFiX run is resumable.

Pls help.

Hi @rkanchi, there is not enough information here for us to help you.
Is there anything in the .LOG files or other files?

This job runs on Linux with 4 SMP threads, but on Windows I get the same failure you are seeing, without any helpful messages. The job runs on Windows if I use the non-SMP solver.

Unfortunately we do not have good debugging tooks on Windows and I’m not sure I’ll be able to fix this, since I don’t have good visibility into what’s going wrong.

Is it possible to set up a Linux machine for your work? You may find other advantages to doing so as well (jobs tend to run faster, debugging code is easier, etc).

Okay I will see what I can do

Okay here is something:
Mfix 23.2 version required me to build SMP solver. I did that and it worked. 23.3.2 and 23.4.1 don’t work. You could look into why…but yeah. Hope it helps.

Thanks.

We started supplying a pre-built SMP solver as a convenience to users. You can certainly try building it yourself, maybe that will work…

I did both on both versions. Did not work
