Does this problem contain a temperature equation?

## Syntax

tempFlag = udfHasTemp( udfHd ) ;

## Type

AcuSolve User-Defined Function Global

## Parameters

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

## Return Value

- tempFlag (integer)
- Flag indicating whether or not this problem has temperature equation.

- 0
- No
- 1
- Yes

## Description

This routine determines if this problem contains a temperature equation. For
example,

```
Integer tempFlag ;
...
tempFlag = udfHasTemp( udfHd ) ;
if ( tempFlag == 1 ) {
/* Logic if temperature equations exist */
...
)
```

## Errors

This routine expects a valid udfHd.
