Hi, everyone. The following message appears when I activate the heat mass coupling in DPM panel. "Time step too small in stiffbs:
Time step too small in stiffbs: dt = 3.819282e-21, t = 4.316239e-04 0 y = 2.000002e-11 dy/dt = -1.075370e+03 1 y = 2.312000e+02 dy/dt = 0.000000e+00 Time step too small in stiffbs: dt = 3.589703e-21, t = 4.311432e-04 0 y = 2.000000e-11 dy/dt = -1.076570e+03 1 y = 2.312000e+02 dy/dt = 0.000000e+00 Time step too small in stiffbs: dt = 3.513279e-21, t = 4.311310e-04 0 y = 2.000002e-11 dy/dt = -1.076599e+03 1 y = 2.312000e+02 dy/dt = 0.000000e+00 Can you explain it?Thank you very much! |
