# gp.force.app

Syntax

v := gp.force.app(gp)

Get the total applied force at a gridpoint. This includes all sources, including forces due to gravity.

Returns: v - total applied force vector z - zone pointer

Component Access

f := gp.force.app (gp)->x

f := gp.force.app.x(gp)

Get the $$x$$-component of the total applied force at a gridpoint.

Returns: f - $$x$$-component of the total applied force vector gp - zone 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 (gp.force.app(gp,<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 := gp.force.app.y(gp)
f := gp.force.app.z(gp)
