# udfGetElmWDetJ()

Return the weighted determinant of the element Jacobian at the quadrature point.

## Syntax

wghtDetJac = udfGetElmWDetJ( udfHd ) ;

## Type

User Defined Element

## Parameters

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

## Return Value

- wghtDetJac (Real*)
- Pointer to one dimensional real array of the weighted determinant of the Jacobian at the element quadrature point. The array dimension is the number of elements, nItems.

## Description

```
Real* wghtDetJac ;
Real wDetJ ;
Integer elem ;
...
wghtDetJac = udfGetElmWDetJ( udfHd ) ;
for ( elem = 0 ; elem < nItems ; elem++ ) {
wDetJ = wghtDetJac[elem] ;
...
}
```

## Errors

- This routine expects a valid udfHd.
- This routine may only be called within a Body Force, Material Model or Component Model user function.
