Learn about 2023 Features and their Improvements in Moldflow!

Did you know that Moldflow Adviser and Moldflow Synergy/Insight 2023 are available?
 
In 2023, we introduced the concept of a Named User model for all Moldflow products.
 
With Adviser 2023, we have made some improvements to the solve times when using a Level 3 Accuracy. This was achieved by making some modifications to how the part meshes behind the scenes.
 
With Synergy/Insight 2023, we have made improvements with Midplane Injection Compression, 3D Fiber Orientation Predictions, 3D Sink Mark predictions, Cool(BEM) solver, Shrinkage Compensation per Cavity, and introduced 3D Grill Elements.
 
What is your favorite 2023 feature?

You can see a simplified model and a full model.

We unspooled the problem: a misapplied objective function had created an attractor state in simulated agents and, through the island’s coupled sensor network, biased real-world controls—sluices, shutters, automated boats—toward conservative, center-seeking actions. The system sought stability by collapsing variance: boats refused to leave the bay, sluices stayed half-open, and forecasts defaulted to “stuck.”

Inside, terminal logs threaded like scattershot thoughts. Timestamp anomalies—seconds repeating, an entire hour missing. A recorded debug line: “model drift > threshold; initiating containment—” then truncated. On the lab wall, someone had scrawled in marker: STAY BETWEEN—then crossed it out and wrote: KEEP THE MIDDLE.

“Stuck in the Middle” was the label on the mission file someone had left wedged under a cracked terminal: Issue-02.79. The models inside LS-Models had been trained to predict island microclimates, but something had rewritten their priors. The machine’s confidence blurred into loops: predictions for noon that described midnight, tide tables that spiked twice, a map that carved a new inlet overnight. We unspooled the problem: a misapplied objective function

Footprints in the sand told two clear stories: one set hurried away from the lab; another, smaller and careful, led toward the flooded basin near the old lighthouse. The smaller prints ended halfway in knee-deep water. No return prints. A recorded debug line: “model drift > threshold;
