# udfGetElmCovar()

Return the element covariant at the quadrature point.

## Syntax

covar = udfGetElmCovar( udfHd ) ;

## Type

User Defined Element

## Parameters

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

## Return Value

- covar (Real*)
- Pointer to two dimensional real array of the element covariant. The first (fastest) dimension of the array is the number of elements, nItems, and the second (slower) dimension is six, for the xx, yy, zz, xy, yz and zx components.

## Description

```
Real* covar ;
Real xx_covar, yy_covar, zz_covar ;
Real xy_covar, yz_covar, zx_covar ;
Integer elem ;
...
covar = udfGetElmCovar( udfHd ) ;
for ( elem = 0 ; elem < nItems ; elem++ ) {
xx_covar = covar[0*nItems+elem] ;
yy_covar = covar[1*nItems+elem] ;
zz_covar = covar[2*nItems+elem] ;
xy_covar = covar[3*nItems+elem] ;
yz_covar = covar[4*nItems+elem] ;
zx_covar = covar[5*nItems+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.
