Step 7: Non-Reacting Flow Solution

1.   Disable Volumetric for solving non-reacting flow.

Models Species Edit...

(a)   Disable Volumetric in the Reactions group box.

(b)   Click OK to close the Species Model dialog box.

  You will be running a non-reacting solution to establish the flow.

2.   Retain the default Under-Relaxation Factors.

3.   Enable residual plotting during the calculation.

Monitors Residuals Edit...

(a)   Retain the default settings and close the Residual Monitors dialog box.

4.   Initialize the flow field using the boundary conditions set at velocity-inlet.

Solution Initialization

(a)   Select velocity-inlet from the Compute from drop-down list.

(b)   Click Initialize

5.   Save the case file ( surface-non-react.cas.gz).

File $\rightarrow$ Write $\rightarrow$ Case...

6.   Start the calculation by requesting 200 iterations.

Run Calculation

(a)   Enter 200 for Number of Iterations and click Calculate.

  The solution will converge in approximately 120 iterations.
