Ensure the feed system is perfectly connected to the part geometry. Disconnected beams or nodes force the solver to calculate a disjointed volume, causing an immediate crash. Step 2: Increase System Virtual Memory (Pagefile)
If the issue persists, try repairing or reinstalling Moldflow:
In many cases, your primary analysis (the "parent" job) may start perfectly fine because a license is available. However, because DOE analyses spawn multiple child jobs
For solvers running on Linux, the environment variables must point correctly to the Autodesk Licensing Service: autodesk moldflow error 99998
: The computer cannot resolve the license server's hostname to an IP address, common when using a VPN or across different network domains. Step-by-Step Troubleshooting Verify License Status (LMTools) on your license server, go to the Server Status tab, and click Perform Status Inquiry
Autodesk Moldflow typically means the solver (Insight) cannot find a valid license to start the analysis. This often happens because the license server is unreachable, the license file is missing the solver component, or the local license configuration is incorrect. 🛠️ Quick Troubleshooting Checklist
Avoid launching multiple high-resource simulations simultaneously on local machines with less than 64 GB of RAM. Ensure the feed system is perfectly connected to

Autodesk Moldflow is an industry-leading simulation tool used to analyze and optimize injection molding processes. However, even the most powerful software can encounter errors that disrupt workflows. One of the most common and frustrating errors encountered by users, particularly in Moldflow Insight (solver) environments, is .
Error 99998 is a fatal solver error. It indicates that the simulation engine stopped working abruptly before completing the analysis. Unlike specific error codes that point directly to a missing boundary condition or a venting issue, 99998 means the solver encountered a problem it could not gracefully recover from or categorize. Primary Causes of Error 99998 However, because DOE analyses spawn multiple child jobs
Sometimes, extreme input values cause the solver matrices to diverge.
Moldflow relies on the SCM to handle job queues. If the SCM database becomes bloated or corrupted, it will drop jobs mid-simulation, registering them as Error 99998.
If the crash occurs during a specific process (like the packing or warping phase), the mathematical algorithms may be failing to converge. Open and go to Advanced Options . Click Edit next to Solver Parameters.
