11.7.3 Simulation

This section explains the settings to run the multicomponent mixing simulation

Creating Monitoring Points

The steps are as follows:

1. On the Geometric Entities Panel toolbar, click Create a Monitoring Point icon twice, to create points. The Point 01 and Point 02 are created under Points.
2. Rename Point 01, Point 02 and specify their Position values as shown in Table 11.9 in the Geometry Tab of Properties Panel (see, Figure 11.167).

Points	Rename as	Position values (m)
Point 01	throat_centre_point	0.17, 0, 0
Point 02	throat_edge_point	0.17, 0.01, 0

Table 11.9 - Monitoring point

Note: Monitoring points need to be created before running the simulation for recording data (see, Figure 11.168). The position of a points may also be dragged to a new location using the Select option (Toolbar) and the Left Mouse Button.

Simulation Settings

1. Select Simulation Panel and enable Steady.
2. Enter Number of Iterations as 500 and Result Saving Frequency as 100 (see, Figure 11.169).
3. Select Start from Initial Values to start from specified initial values.
4. After you save the project, click Start to run the simulation.
5. The result file is saved as a .sres file in the working folder (Example : "projectname_1000.sres").

Note: The default Converge Criterion is 0.001 for Steady State Simulation. When the residuals for all the variables drop by three orders or the maximum Number of Iterations is reached, the calculation stops and saves the result files in sres files.
