udfGetSdCrd()

Return the nodal coordinates for the nodes in the subdomain.

Syntax

crd = udfGetSdCrd( udfHd ) ;

Type

AcuSolve User-Defined Subdomain Routine

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, and the second (slow) dimension is three, for the x, y and z coordinates.

Description

This routine returns the nodal coordinates for the subdomain. If mesh displacement is active, the returned coordinates are for the current (deformed) configuration. For example,

Real* crd ;
Real x, y, z ;
Integer node, nNodes ;
...
nNodes = udfGetNSdNodes( udfHd ) ;
crd = udfGetSdCrd( udfHd ) ;
for ( node = 0 ; node < nNodes ; node++ ) {
   x = crd[0*nNodes+node] ;
   y = crd[1*nNodes+node] ;
   z = crd[2*nNodes+node] ;
   ...
}

Errors

This routine expects a valid udfHd.
This routine may only be called within an external code.
