# gp.force.app

Syntax

## Vector Access

v := gp.force.app(gp<,i>)

Get the total applied force at a gridpoint. This includes all sources, including forces due to gravity. Returns a vector, unless an optional component argument i is supplied, in which case it returns the component value.

Returns: v - total applied force vector or component z - zone pointer i - optional vector component, from 1 to 3

## Component Access

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

Get the $$x$$-component total applied force vector.

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

Get the $$y$$-component total applied force vector.

Returns: f - $$y$$-component total applied force vector z - zone pointer
f := gp.force.app.z(gp)

Get the $$z$$-component total applied force vector.

Returns: f - $$z$$-component total applied force vector z - zone pointer
