Solver Enhancements for 2026.0.1

The following enhancements to the analysis solvers provide you with better solutions and improved accuracy.

Multiple opening and closing of Valve Gates

At maximum, two open and close cycles are possible for each valve gate controller in a single 3D Flow analysis. In previous Moldflow versions, the possible number of open and close cycles of each controller was unlimited. Midplane and Dual Domain flow analyses do not have any limit to the number of open and close cycles of each valve gate controller.

Valve Gate Control by Pressure

When valve gate open/close actions are set to be triggered by pressure, Moldflow 2026.0.1 may produce slightly different results compared to previous versions. This is due to enhancements in how the local pressure trend is evaluated at the trigger location. For all other valve gate control types, results are expected to remain unchanged.

Venting Analysis for Chemical Foam Molding process

The Venting Analysis feature is now available for Chemical Foam Molding process in 3D analysis. To perform the Venting analysis, follow the instructions to properly set up venting analysis locations and enable the Perform venting analysis option on the Venting Analysis tab within the solver parameters dialog.

Scorch index result for 3D Flow reactive molding analyses

A new Scorch index result is added. It is used primarily for rubber processing. Scorch index is the fraction of reaching the induction time, the time for elastomers to start the main curing reaction. A Scorch index below 1.0 indicates that the main curing reaction is not yet started. A Scorch index above 1 indicates that curing is advanced and may affect the quality of the molding, causing defects known as scorch marks.

The new result is displayed as an animated plot and the maximum predicted scorch index is added to the analysis log.
