Closure Calculation Time

Closure calculation time

Despite bucket-sorting the closure calculation is still numerically intensive, and can take some time to perform. Therefore the following strategy is adopted:

  • The closure calculation is only carried out when actually required. For example when a plot is requested, or scalar data extracted
  • Once calculated the results are stored, so that subsequent plots, changes of contour values, etc, are fast as no recalculation is required.

The closure calculation has to be repeated when:

  • Either the workpiece or die contents are changed, by adding or removing elements.
  • Any closure parameter (thickness, bucket size, etc) is changed.
  • A new complete state is read in.
  • A velocity arrow or contact force vector plot is carried out. (Since the temporary storage space used is overwritten by these two plotting modes.)

While closure is being calculated a "progress" bar is written to the dialogue box stating how far, in %age terms, the calculation has gone. You can use STOP to terminate it prematurely at any time.
