Warning: Y_G_N > Y_EQ
« on: June 02, 2019, 08:08:47 am »

I am using PyroSim V2018.3.1210. When running a simulation with ESFR sprinklers protecting a 17 foot storage array, the simulation fails at 63.4 seconds into the simulation, about the same time as 1st sprinkler actuation and then produces the following errors related to particles:

WARNING: Y_G_N > Y EQ. Mesh: 3, Particle: 46
WARNING: Delta TMP_G. Mesh: 3, Particle 46
WARNING: TMP_G_N < TMP_D_N. Mesh: 3, Particle 46

This error message string is repeated hundreds of times for differing particle ID's.

Does anyone have insight into what this error message is indicating and the source of the failure?

Thank you.

Have you tried running this simulation in the latest version of PyroSim?
