# udfGetEbcNElemNodes()

Return the number of element nodes for the boundary element set.

## Syntax

nElemNodes = udfGetEbcNElemNodes( udfHd ) ;

## Type

AcuSolve User-Defined Example Boundary Condition

## Parameters

udfHd
The opaque handle (pointer) which was passed to the user function.

## Return Value

nElemNodes (integer)
Number of element nodes for the boundary element set.

## Description

This routine returns the number of element nodes for the boundary element set. This depends only on the topology (tets, wedges, and so on) of the elements in the boundary element set. For example,
Integer nElemNodes ;
...
nElemNodes = udfGetEbcNElemNodes( udfHd ) ;

## Errors

• This routine expects a valid udfHd.
• This routine may only be called within an Element Boundary Condition user function.
