gp.fix

Syntax

Vector Access

v := gp.fix(gp<,i>)

gp.fix(gp<,i>) := v

Get/set a vector indicating gridpoint fixity. A non-zero component value indicates that the degree-of-freedom is fixed in the local gridpoint system.

Returns:

v - fixity condition vector or component value; non-zero indicates a fixed degree of freedom

Accepts:

v - fixity condition vector or component value; non-zero indicates a fixed degree of freedom

Arguments:

z - zone pointer

i - optional vector component, from 1 to 3

Component Access

b := gp.fix.x(gp)

gp.fix.x(gp) := b

Get the fixity component in the \(x\)-direction in the gridpoint local coordinate system.

Returns:b - \(x\)-component fixity condition Accepts:b - \(x\)-component fixity condition Arguments:z - zone pointer

b := gp.fix.y(gp)

gp.fix.y(gp) := b

Get the fixity component in the \(y\)-direction in the gridpoint local coordinate system.

Returns:b - \(y\)-component fixity condition Accepts:b - \(y\)-component fixity condition Arguments:z - zone pointer

b := gp.fix.z(gp)

gp.fix.z(gp) := b

Get the fixity component in the \(z\)-direction in the gridpoint local coordinate system.

Returns:b - \(z\)-component fixity condition Accepts:b - \(z\)-component fixity condition Arguments:z - zone pointer
