ball results command

Syntax

ball results keyword ...

Primary keywords:

active    add-attribute    remove-attribute

Modify the usage of the ball results logic. This logic allows for a reduced version of the model state (i.e., ball geometries plus ball attributes) at different instances of time to be output as binary files. The ball result can be used to re-create the model state, acting as a utility for efficient post processing (e.g., movie generation, residence time calculations, etc.). A ball result file DOES NOT replace a PFC model state file and models re-created with this logic should not be cycled. See the model results command to specify when results files are created and how to import these files subsequently.

active b

Set the status of ball result creation.

add-attribute s

Add the ball attribute s (as defined in the ball attribute command) to be recorded in the ball result. When the result is re-created, this attribute will be filled. All ball attributes can be listed with the ball list attribute command. Ball group and extra variables can also be added using the group and extra keywords.

remove-attribute s

Remove the ball attribute s (as defined in the ball attribute command) to be recorded in the ball result. Ball group and extra variables can be removed using the group and extra keywords.

Usage Examples

Set program to store model results and add ball velocity to the results file.
