udfGetNbcCrd()
Return the nodal coordinates for the nodal boundary condition.
Syntax
crd = udfGetNbcCrd( 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 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 nodal coordinates. If mesh displacement is active, the returned
coordinates are for the current (deformed) configuration. For
example,
Real* crd ;
Real x, y, z ;
Integer node ;
...
crd = udfGetNbcCrd( 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.
