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.
