I was trying to get the velocity of debris after TDE in a large distance in a simulation.But when I try to simulate TDE and let the debris evolve freely,calculation stopped at a distance of several $\times R_{\mbox{sun}}$ instead of larger distance,for our purpose,e.g,1pc.
And errors were:
WARNING! cons2prim: Internal energy < 0 on particle 5049: u = -4.811E+03
FATAL ERROR! eos: utherm < 0 : u = -4.811E+03
something else has gone wrong in your simulation (suggest to have a look with splash)
or a "known issue" as detailed in Liptai & Price (2019) it is not fully guaranteed that viscous dissipation is always positive definite in the full GR case
suggest to try using a smaller C_cour to see if that fixes the issue
