Hello,<\/p>\n

I am trying to simulate the transient cooling of a flate aluminum plate from an initial temperature of 800K to the DPM liquid temperature around 300K using a flat fan atomizer dpm simulation. I am running into an issue around 1.6 seconds into the 5 second simulation, ~9250 iterations with 50 iterations per time step, the residual values explode causing a floating point error and a bunch of cells limited at 1K or 5000K. I have included a few figures which show the locations of the 5000K and 1K cells and the temperature gradient on the surface at the last time step. Up until this last time step the simulation is able to run and shows the plate cooling a rate that is expected. I have a minimum orthogonal value of 0.1 and average of around 0.8. I can answer any questions you have for me, but any help would be greatly appreciated.<\/p>\n
