A new solver predicts with improved accuracy the location and depth of
sink marks.
The new sink mark solver analyzes geometric
features that are likely to induce sink marks, for example, ribs, bosses, gussets, and
internal fillets. The solver then uses this geometric information to perform a localized
analysis to predict the sink marks' depths. For example, the image above shows improved
sink mark predictions at the surface of a game controller part that has internal boss
and rib features. 
The sink mark results are updated as follows:
- The Sink Marks plot from
the Fill results is renamed to Sink Marks Estimate at
End of Fill.
- A new plot, Sink Marks at Ejection,
is available with the Pack results.
- The Sink-Mark Profile plot from the
Warp results is removed, as the prediction of sink marks based on the conditions
at the end of filling is not accurate. Instead, you can refer to the Sink Marks at Ejection plot to review the
location and depth of sink marks.
The new sink mark solver is available
only for solid-hybrid and solid-hexahedral mesh procedures. The shell mesh procedure
continues to use the current sink mark solver.
