<div dir="ltr"><div id="gmail-:mw" class="gmail-a3s gmail-aiL"><div dir="ltr">Dear Friends,<div>I would really appreciate your help with the following issue:</div><div>I
am running a SBlast simulation in 3D - hydrodynamic expansion of initial perturbation with two fluids (3D graph of initial perturbation of internal energy is attached - energyZ). Simulation starts to execute
perfectly - initial ball-shaped perturbation starts to expand but
between 16th and 17th time step (please see attached slices of distributions of density, pressure and internal energy) something
happens - in a few cells values of density, pressure and internal
energy become crazy ~10^38 and code crashes after that with Floating
point exception - erroneous arithmetic operation. Any ideas on what can
cause this problem or how can I track it down would be greatly appreciated!<br></div><div>Thank you very much!</div></div></div></div>
