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
----------------------------------------------------------------------
| Equation | Rate | RMS Res | Max Res | Linear Solution |
+----------------------+------+---------+---------+------------------+
| U-Mom | 0.00 | 0.0E+00 | 0.0E+00 | 0.0E+00 OK|
| V-Mom | 0.00 | 1.3E+00 | 1.4E+00 | 2.9E-04 OK|
| W-Mom | 0.00 | 0.0E+00 | 0.0E+00 | 0.0E+00 OK|
| P-Mass | 0.00 | 3.5E-07 | 3.4E-06 | 41.8 1.0E+02 F |
+----------------------+------+---------+---------+------------------+
| H-Energy | 0.00 | 3.6E-03 | 7.0E-01 | 5.2 3.6E-06 OK|
+----------------------+------+---------+---------+------------------+

any idea to avoid this error

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

What are you modelling?
