Autodesk Moldflow is the industry standard for injection molding simulation, but encountering analysis failures can disrupt your engineering workflow. One of the most common and frustrating issues is . Because this error acts as a generic catch-all indicator for unexpected solver crashes, identifying the root cause requires a systematic approach.
She restarted the solver. Same error. She reduced the solver memory allocation. Same error. She turned off parallel processing. Same error.
: The License Configuration tool is set to the wrong license type or is pointing to an incorrect license server. autodesk moldflow error 99998
Understanding and Fixing Autodesk Moldflow Error 99998 Autodesk Moldflow Error 99998 is a generic solver crash error that stops an injection molding simulation from completing. It indicates that the simulation engine closed unexpectedly, but it does not specify the exact root cause. Common Causes of Error 99998
Uncheck "Automatically manage paging file size for all drives." Autodesk Moldflow is the industry standard for injection
: If the server takes too long to respond (common over VPNs), the request fails.
Ensure your workstation uses certified enterprise graphics drivers (e.g., NVIDIA RTX Enterprise/Quadro drivers) configured for compute-heavy workloads rather than gaming performance. She restarted the solver
: All available seats are currently in use by other team members, or the subscription has simply expired.
Extreme injection pressures or unrealistic volumetric flow rates caused numerical divergence.
: A large clock difference between the client machine and the license server can cause the security check to fail. Step-by-Step Troubleshooting Guide 1. Verify License Configuration (Moldflow 2023 and Newer)
The client machine is pointing to the wrong license server, uses an incorrect port, or has an outdated Network License Manager (LMTools) .
