gp.disp.small

Syntax

v := gp.disp.small(gp)

gp.disp.small(gp) := v

Get/set the small displacement vector for the gridpoint.

Small displacements are incremented from velocity and timestep only in the small-strain model. See the command model large-strain. The small-strain vector field is used in the interface logic to calculate overlaps.

Returns:

v - small displacement vector

Accepts:

v - small displacement vector

Arguments:

gp - a zone gridpoint pointer

Component Access

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

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

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

Get the \(x\)-component of the small displacement vector for the gridpoint.

Returns:

f - \(x\)-component of the small displacement vector

Accepts:

f - \(x\)-component of the small displacement vector

Arguments:

gp - a zone gridpoint pointer

Access other vector components (\(y\), \(z\) (3D ONLY)) 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.small(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.small.y(gp)

f := gp.disp.small.z(gp)
