Description:The names of the variables that this VectorPostprocessor operates on
SideValueSampler
Sample variable(s) along a sideset, internal or external.
The data output to CSV is output with the columns listed below. The declared vectors use the same names.
the id of the element that the quadrature point, on the side, belongs to.
the values of the requested variables, with a column named after each variable. On internal sidesets, finite volume variables use an inverse distance weighted average to determine the face value.
the X, Y, Z coordinates of the quadrature points on the side. In case of finite volume variables this is the cell centroid of the face.
commentnote:General sampling
The SideValueSampler samples variables on the specified boundary on element side quadrature points. For more flexible sampling, use the PositionsFunctorValueSampler.
Example input syntax
In this example, variable u and v are the solutions of two boundary value diffusion problems. Their value along the top boundary and along the center internal sidesets are reported using two SideValueSampler. The rows in the CSV output are sorted according the x coordinate along the boundary for the former, and the element id for the latter.

[]Input Parameters
- _auto_broadcastFalse
Default:False
C++ Type:bool
Controllable:No
- contains_complete_historyFalseSet this flag to indicate that the values in all vectors declared by this VPP represent a time history (e.g. with each invocation, new values are added and old values are never removed). This changes the output so that only a single file is output and updated with each invocation
Default:False
C++ Type:bool
Controllable:No
Description:Set this flag to indicate that the values in all vectors declared by this VPP represent a time history (e.g. with each invocation, new values are added and old values are never removed). This changes the output so that only a single file is output and updated with each invocation
- parallel_typeREPLICATEDSet how the data is represented within the VectorPostprocessor (VPP); 'distributed' indicates that data within the VPP is distributed and no auto communication is performed, this setting will result in parallel output within the CSV output; 'replicated' indicates that the data within the VPP is correct on processor 0, the data will automatically be broadcast to all processors unless the '_auto_broadcast' param is set to false within the validParams function.
