33.15 Solution Initialization Task Page

The Solution Initialization task page allows you to define values for flow variables and initialize the flow field to these values. See Section  26.9.1 for details about using this dialog box.

Controls

Compute from   is a drop-down list of zones; the default values for applicable variables will be computed from information contained in the zone that you select from this list. The computation will occur when you select the required zone, and the variable values will be displayed in Initial Values. You can also choose the all-zones item in this list to compute average values based on all zones.

Reference Frame   indicates whether the initial velocities are absolute velocities ( Absolute) or velocities relative to the motion of each cell zone ( Relative to Cell Zone). This selection is necessary only if your problem involves moving reference frames or sliding meshes. If there is no zone motion, both options are equivalent.

Initial Values   displays the initial values of applicable variables. You can use Compute from to compute values from a particular zone, or you can enter values directly.

Initialize   initializes the entire flow field to the values listed.

Reset   resets the fields to their "saved'' values.

Patch...   opens the Patch dialog box.

Reset DPM Sources   allows you to reset the interphase sources/sinks of momentum, heat, and/or mass to zero. This item is available when you perform coupled discrete phase calculations. See Section  23.6.2 for details.

Reset Statistics   can be used to both initialize the flow statistics and reset the flow statistics after you have gathered some data for time statistics. This item is available when you perform unsteady calculations and have enabled the Data Sampling for Time Statistics option in the Run Calculation task page. See Section  26.12.1 for details.
