I had ansys fluent crash and seemingly corrupt my project
I have a eulerian mixing problem with a transient simulation of 2 fluids injecting through concentric tubes at 2 different constant velocities and mixing in a common tube.
My phase 2 material seemingly dissipates across the entire volume at time step 3.
I would expect the phase 2 material (smaller tube to progress down the tube as time progresses). It seems like the phase 2 inlet boundary condition is suddenly set to 0 at time step 3 or something like that... all time after 3 appear similar.
(note before the crash I was using a pulsatile velocity on phase 1 via a UDF but after noticing this volume fraction problem switched it back to a constant) See attached slide images:
