Set the dropdown level to match your entitlement precisely (e.g., ).
If you are still experiencing the error, it is recommended to review the adskflex log files on the license server for more specific error codes.
If you manually unpack thin clients, the core solver will return Error 99998 unless the configuration framework is built. Run the terminal shell utility bundled inside your source installation bundle:
If the error persists after these steps, it is likely a specific related to a unique combination of material data and process settings. To help you get back to your simulation, could you tell me: Which version of Moldflow (2021, 2023, 2024) are you using?
Follow these steps in order to isolate and resolve the issue. Step 1: Clean the Mesh and Repair Geometry autodesk moldflow error 99998
If Flow fails immediately, the issue is concentrated within the part geometry mesh or the core polymer material properties. Advanced Preventative Strategies
Review boundary conditions and process settings
Users often find that separate installations for the UI and solver can cause confusion.
Navigate to your local temporary directories (typically C:\Users\ \AppData\Local\Autodesk\Moldflow... or your designated solver scratch directory). Set the dropdown level to match your entitlement
Ensure the (e.g., Network) and License Level (Standard, Premium, or Ultimate) match your subscription.
The screen flickered. The command line interface, usually so clinical and quiet, threw up a wall of red text. At the very bottom, framed by asterisks, was the message:
Always check the Autodesk License Parser first to confirm your .lic file actually contains the Insight solver feature.
While error 99998 in Autodesk Moldflow can be frustrating, there are potential solutions and workarounds available. If you're experiencing this issue, try the troubleshooting steps outlined above. If the problem persists, you may want to reach out to Autodesk support or consult with a Moldflow expert for further assistance. Run the terminal shell utility bundled inside your
is a critical license-related error that prevents simulations from running. In most cases, the error message takes one of the following forms:
Run ...AdskLicensingInstHelper.exe list to verify changes.
When you see Error 99998, don’t trust the solver’s silence. Go hunting in the output files. It’s almost always a localized mesh or thermal instability near the end of fill — or occasionally a disk full, memory limit, or a corrupted material file. But mostly? It’s the solver saying “something went wrong” without telling you what.
While rare, a material file ( .udb or proprietary .materials ) can have a corrupted rheological or PVT data set. When the solver calls the Cross-WLFL viscosity model parameters, it might receive a NaN (Not a Number) or infinite value. The solver cannot compute pressure drop and crashes.
