block.gp.force.reaction

Syntax

v := block.gp.force.reaction(bgpp)

Get the reaction force at the gridpoint. Reaction forces are the forces resulting from the stress in a zone acting against a fixed boundary. Only deformable blocks have reaction forces.

Returns:

v - reaction force vector

Arguments:

bgpp - block gridpoint pointer

Component Access

f := block.gp.force.reaction (bgpp)->x

f := block.gp.force.reaction.x(bgpp)

Get the $x$-component of the reaction force at the gridpoint.

Returns:

f - $x$-component of the reaction force vector

Arguments:

bgpp - block gridpoint pointer

Access other vector components ($y$, $z$) by substituting the component name where $x$ appears above. See Member Access Operator for information about accessing members from data types using ->.

Deprecated Component Access

Component access by adding an optional integer in the function arguments (block.gp.force.reaction(bgpp,<int>)) is deprecated. It remains available but will not be supported in future versions. See Component Access with Integers in FISH on the Deprecated Commands and FISH page for details.

This is hidden. Added to include remaining vector component access functions for inline help.

f := block.gp.force.reaction.y(bgpp)

f := block.gp.force.reaction.z(bgpp)
