# udfGetTimeAlpha()

Return the time at the alpha point of the generalized-alpha time marching algorithm.

## Syntax

timeAlpha = udfGetTimeAlpha( udfHd ) ;

## Type

AcuSolve User-Defined Function Global

## Parameters

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

## Return Value

- timeAlpha (real)
- Time at the alpha point of the generalized-alpha time marching algorithm.

## Description

This routine returns the time at the alpha point of the generalized-alpha time marching
algorithm. The element residual is evaluated at
this time; hence if a material model or other
element data is dependent on time, this function
must be used to get the time. For
example,

```
Real timeAlpha ;
...
timeAlpha = udfGetTimeAlpha( udfHd ) ;
```

## Errors

This routine expects a valid udfHd.
