Use the Grain Counter feature to compute information about grains that are located in a set of selected domains. The counter can include all grains or may be restricted to grains corresponding to a specific release feature or a Grain Properties node. Computed variables are the number of grains transmitted, the number of grains transmitted at the final time, the transmission probability, and a logical expression which can be used to filter the rendered grains during results processing.

Select an option from the Grain selection list to specify whether the Grain Counter collects information based on Release feature (the default) or Grain properties.

If Release feature is selected, select an option from the Release feature list. If All (the default) is selected, the Grain Counter collects information about all grains in the selected domains, regardless of how they were released. Alternatively, select a grain release feature from the list, and then only the grains produced by that release feature are counted.

If Grain properties is selected from the Grain selection list, select an option from the Released grain properties list. If All (the default) is selected, the Grain Counter collects information about all grains in the selected domains, regardless of their grain properties. Alternatively, select a grain properties feature from the list, and then only the grains associated with the selected Grain Properties node are counted.
