stop in parallel run.what can be the cause?
 
could someone help with this error?
thanks.

In case you missed it, the iteration terminated because the number of iterations for time step in temperature calculation exceeded maximum limit (default defined as 100/time step). Usually this can be fixed by choosing an appropriate boundary condition, or, sometimes, changing the time step size.

thank you dear traib.but how did you find that the error is because of temperature?e has only 3 iterations at the last iteration.thanks.

Temperature is obtained from energy value after energy calculation using energy-temperature inversion method. Check src/thermophysicalFunctions/specie/thermo/specieThermo.H to see how this works.
