Early Termination of Simulations

[Andy]

Hi,

I'm running on windows and everything seems to work fine except simulations are terminating early with no errors message.  For example the 2d dam break example will run to 38% complete and terminate - similar for others.  When I view the results all are fine up to the point they terminate.  Given no errors/warnings are there any suggestions on how to debug this issue or ideas what it could be?

Thanks

Andy

Note: Using: PySPH==1.0b1 from pip install.

Further, I see the same behavior when I run on Ubuntu (WSL) and when I updated to the latest dev version from github (PySPH==1.0b2.dev0) the dam_break_2d example crashes at 39% on both platforms.

Hi Andy,

The wcsph scheme  blows up at that time (as implemented and setup, it may need some tweaking of the artificial viscosity or adjustment of the CFL). You could try with a different scheme: pysph run dam_break_2d --openmp --scheme edac

Use pysph run dam_break_2d --help to see all other schemes available.

cheers,
Prabhu
