Dear All,

I'm trying to solve my model reacting flow in porous media, but I had some error as follows

1. Solving all variables must have at least one isolation solver step process order
- Characteristics: Steady State Solver 1 (sol1 / s1)

2. Failure to find solutions of all parameters
Even minimum parameters scan
Returns the solution does not converge
- Characteristics: Steady State Solver 1 (sol1 / s1)

3. Find undefined value
- Details: In the undefined value equation residual vector.
There are of variable comp1.wO2 vector field has no value or infinite value of 95444 degrees of freedom
The coordinates: (0.0055,0.004, -0.0003), (0.005425,0.004, -0.0003), (0.00535,0.004, -0.0003), (0.005275,0.004, -0.0003), (0.0052,0.004, -0.0003), .. .
- Characteristics: Steady State Solver 1 (sol1 / s1)

What is the meaning of the above error in number of 1, 2, and 3 ?
Thank you very much,
Yusuf
