Autodesk’s Moldflow Insight Ultimate is a high‑fidelity CAE tool for injection‑molding simulation. Version 2016 Multi‑Win64 is still in use by several legacy production lines that rely on its advanced flow and cooling models. An update (released 2025‑12‑15) introduced a series of performance enhancements and bug‑fixes, but also appears to have introduced a stability regression manifested as an abrupt application crash. The term “crack” used by the field team denotes this sudden termination.
The purpose of this report is to provide a structured, reproducible description of the crash so that Autodesk’s engineering team can prioritize a fix and to aid internal stakeholders in mitigating risk while awaiting a patch. This list represents a broad overview of features
This list represents a broad overview of features that could be included in Autodesk Moldflow Insight Ultimate 2016. For specific details, capabilities, and to confirm the exact features, I recommend consulting Autodesk's official documentation or contacting their support team. | Observation | Details | |-------------|---------| | Crash
Technical Incident Report
Subject: Crash of Autodesk Simulation Moldflow Insight Ultimate v2016 Multi‑Win64 (Update)
Report ID: AIM‑INS‑2026‑0414‑01
Date: 14 April 2026
Prepared by: [Your Name], Software Reliability Analyst Build 19044 (21H2)
| Observation | Details |
|-------------|---------|
| Crash Timing | Consistently after ~ 4 min 30 s of solver execution, coincident with the first AMR‑triggered refinement iteration. |
| Memory Footprint | Peak RAM usage recorded by Windows Performance Monitor: 78 GB (well below system capacity). |
| CPU Utilization | ~ 95 % across 20 cores during the period leading up to the crash. |
| Event Viewer | Faulting application name: Moldflow.exe, Faulting module name: MoldflowCore.dll, Exception code: 0xc0000005. |
| Dump Analysis (pre‑liminary) | Mini‑dump (Moldflow_20260414.dmp) shows a null‑pointer dereference inside CMeshRefinement::ApplyRefinement(). |
| Impact on Files | Project file remains intact; however, the unsaved simulation results are lost. The *.log and *.moldproj files are not corrupted. |
| Scope | The issue reproduces only when AMR is enabled with refinement level ≥ 3 on meshes exceeding ~ 1 GB. Disabling AMR or reducing refinement level to 2 avoids the crash. |
