# gp.disp

Syntax

v := gp.disp(gp)
gp.disp(gp) := v

Get/set the displacement vector for the gridpoint.

Note that in FLAC3D, displacement vectors are accumulated from velocities and timesteps every cycle. They have no direct effect on the model state. Displacements can be changed at any time without changing the forces or stresses in the model.

Returns: v - displacement vector z - zone pointer

Component Access

f := gp.disp (gp)->x
gp.disp (gp)->x := f

f := gp.disp.x(gp)
gp.disp.x(gp) := f

Get the $$x$$-component of the displacement vector for the gridpoint.

Returns: f - $$x$$-component of the displacement vector f - $$x$$-component of the displacement 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.disp(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.disp.y(gp)
f := gp.disp.z(gp)
