udfGetNbcRefCrd()
Return the initial condition nodal coordinates for the nodal boundary condition.
Syntax
crd = udfGetNbcRefCrd( udfHd ) ;
Type
AcuSolve User-Defined Nodal Boundary Condition
Parameters
- udfHd
- The opaque handle (pointer) which was passed to the user function.
Return Value
- crd (Real*)
- Pointer to two dimensional real array of initial condition nodal coordinates. The first (fast) dimension of the array is the number of nodes, nItems, and the second (slow) dimension is three, for the x, y and z coordinates.
Description
This routine returns the initial condition nodal coordinates. If mesh displacement is active, the
returned coordinates include the initial conditions for the mesh displacement; that is,
the initial deformed configuration. For
example,
Real* crd ;
Real x, y, z ;
Integer node ;
...
crd = udfGetNbcRefCrd( udfHd ) ;
for ( node = 0 ; node < nItems ; node++ ) {
x = crd[0*nItems+node] ;
y = crd[1*nItems+node] ;
z = crd[2*nItems+node] ;
...
}
Errors
- This routine expects a valid udfHd.
- This routine may only be called within an Nodal Boundary Condition user function.
