Simscape Fluids Blocks that Support Fault Modeling

The table lists each block that supports faults, the fault subelement paths, and whether the block contains fault subelements that depend on parameter settings. You can use these when you interact with block faults from the MATLAB command line.

The fault subelement path is the location in a Simscape model where you can add a fault. Each block represents a model element with one or more subelements. Some of these subelement paths are only available for certain parameter configurations. See the block reference page for the specific block to determine the parameter dependencies for a given fault subelement.
