gp.disp.small

Syntax

Vector Access

v := gp.disp.small(gp<,i>)
gp.disp.small(gp<,i>) := v

Get the small displacement vector for the gridpoint. Returns a vector, unless an optional component argument i is supplied, in which case it returns the component value.

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 or component

Accepts:

v - small displacement vector or component

Arguments:

z - zone pointer

i - optional vector component, from 1 to 3

Component Access

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

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

Returns:f - \(x\)-component small displacement vector
Accepts:f - \(x\)-component small displacement vector
Arguments:z - zone pointer
f := gp.disp.small.y(gp)
gp.disp.small.y(gp) := f

Get the \(y\)-component small displacement vector.

Returns:f - \(y\)-component small displacement vector
Accepts:f - \(y\)-component small displacement vector
Arguments:z - zone pointer
f := gp.disp.small.z(gp)
gp.disp.small.z(gp) := f

Get the \(z\)-component small displacement vector.

Returns:f - \(z\)-component small displacement vector
Accepts:f - \(z\)-component small displacement vector
Arguments:z - zone pointer
