MultiAppUserObjectTransfer
Samples a variable's value in the Parent app domain at the point where the MultiApp is and copies that value into a post-processor in the MultiApp
Description
MultiAppUserObjectTransfer transfers information from a UserObject in the parent/sub application to an AuxVariable in the sub/parent application based on the direction of transfer (to_multiapp/from_multiApp).
The transfer can be restricted to a subdomain using the "block" parameter or a boundary using the "boundary" parameter.
To MultiApp
If the AuxVariable in the sub applications is a nodal AuxVariable, for each node in the sub application the value at the corresponding position in the parent application is queried from the parent UserObject, and this value is set to the AuxVariable at that node. A similar approach is followed for the elemental AuxVariable but with the centroid of the element instead of nodal position.
From MultiApp
For nodal AuxVariable in the parent application, it is first determined whether the node is contained within the bounding box of the sub application. If the parent node lies within a sub application's bounding box, the value of the sub application UserObject at that location is transferred to the parent AuxVariable. A similar approach is followed for the elemental AuxVariable but with the centroid of the parent element instead of nodal position.
When all_parent_nodes_contained_in_sub_app option is set to true, an error is generated if the parent node/element does not lie within the bounding boxes of any of the sub applications. An error is also generated if the parent node/element lies within the bounding boxes of 2 or more sub applications.
Input Parameters
- all_parent_nodes_contained_in_sub_appFalseSet to true if every parent app node is mapped to a distinct point on one of the subApps during a transfer from sub App to Parent App. If parent app node cannot be found within bounding boxes of any of the subApps, an error is generated.
