density equation faild
 

hi all,,,
the first iteration give me false, and then give me ok, so is that big deal..means does that affect the results?

The mass density model has failed

TIME STEP = 1 SIMULATION TIME = 1.0000E+00 CPU SECONDS = 6.536E+00
----------------------------------------------------------------------
COEFFICIENT LOOP ITERATION = 1 CPU SECONDS = 6.552E+00
----------------------------------------------------------------------

any idea to avoid this error

Sounds like you have not initialised pressure, density or temperature properly.

What are you modelling?
