Check Availability: Open LMTools on your server. Go to the "Server Status" tab and click "Perform Status Inquiry." Ensure AMI_STANDARD, PREMIUM, or ULTIMATE seats are actually available.
Kill Rogue Processes: If a previous analysis crashed, a "ghost" process might still be holding the license. Open Task Manager and end any instances of flow.exe, cool.exe, warp.exe, or mhb3d.exe.
Sync Your Clock: Ensure the date and time on your computer match the license server exactly. A large time difference will trigger a security block. 🔧 Step-by-Step Troubleshooting 1. Run the License Configuration Utility
Most 2021+ errors are caused by incorrect configuration paths. Close all Moldflow Synergy windows.
Go to Start Menu > Autodesk Moldflow Insight 202X > License Configuration 202X.
Ensure the correct license level (Standard, Premium, or Ultimate) is selected.
Verify the server name. Use the format port@servername (e.g., 27000@YourServerName). Click Apply and try rerunning the analysis. 2. Increase the License Timeout
If your network is slow, the solver may give up before the server responds.
Right-click This PC > Properties > Advanced System Settings. Click Environment Variables. Under System Variables, click New. Variable Name: FLEXLM_TIMEOUT Variable Value: 10000000 (10 million). 3. Verify Firewall Ports
Firewalls often block the specific ports Moldflow uses to communicate with the solver.
Ensure ports 2080, 27000-27009, and version-specific ports (like 43100 for SCM) are open for both inbound and outbound traffic. 🐧 For Linux Users
If you are running Moldflow on Linux, Error 99998 often means the License Configuration Package was never installed or the environment variable is missing.
Install the package: Run the .sh installer found in your Moldflow download files.
Update the Address: Open /etc/opt/Autodesk/ami20XX and ensure ADSK_SERVICE_ADDRESS points to your license service host:port. If these steps don't work, could you tell me:
Which version of Moldflow are you using (e.g., 2021, 2023, 2024)? Are you using a Network License or Named User (Sign-in)? autodesk moldflow error 99998 full
Did this start happening after a recent update or a new installation?
I can provide more specific registry paths or command-line fixes based on your setup.
The dreaded Error 99998 in Autodesk Moldflow is a general solver failure that usually points to a breakdown in communication between the analysis engine and your computer’s hardware or temporary storage. When you see the "Full" designation attached to this error, it typically means the software has run out of space—either physically on your drive or within its allocated memory. 🛠️ Immediate Fixes for Error 99998 1. Clear Your Temporary Files
Moldflow creates massive scratch files during calculations. If your C: drive or designated Temporary Directory is full, the solver will crash instantly.
Locate your temporary folder (usually C:\Users\[Username]\AppData\Local\Temp). Delete all files beginning with s_ or mdt. Empty your Recycle Bin. 2. Check Disk Space and Project Location
Running simulations directly from a Network Drive or a Cloud Folder (like OneDrive or Dropbox) often triggers this error due to latency or "file in use" locks. Move your project (.sdy file) to a local SSD.
Ensure you have at least 2x the expected project size in free disk space. 3. Reset the Simulation Job Manager
Sometimes the communication link between the interface and the solver gets "stuck." Open the Simulation Job Manager. Cancel any "Hung" or "Failed" jobs.
Restart the service via the Windows Services menu (services.msc) by looking for Autodesk Simulation Job Manager. 🔍 Deep Dive: Why Does This Happen? Potential Cause What is happening? Mesh Density
Your mesh is too fine, creating more equations than your RAM can handle. Virtual Memory
Your Windows Page File is too small to handle the overflow from your RAM. Permissions
The solver doesn't have "Write" access to the temporary results folder. Antivirus
Your security software is scanning files while Moldflow tries to write to them. 💡 Pro Tips to Prevent Recurrence ⚙️ Optimize Your Hardware Settings
Increase Page File Size: Set your Windows Virtual Memory to at least 1.5x your physical RAM. Check Availability: Open LMTools on your server
Update Graphics Drivers: Ensure your GPU drivers are certified for Autodesk products.
Clean Boot: Close memory-heavy applications like Chrome or Outlook before starting a long-sequence analysis. 📐 Refine Your Model
Use Symmetry: If your part is symmetrical, use symmetry constraints to cut the element count in half.
Check for Mesh Errors: Overlapping elements or high aspect ratios can cause the solver to "diverge," leading to a 99998 crash.
If you’ve cleared your drive and the error persists, I can help you dig deeper. To narrow it down, tell me: How many elements are in your current mesh?
Are you running a Fill+Pack or a more complex Cool+Fill+Pack+Warp sequence? How much Free Space is currently on your C: drive?
Knowing these details will help us determine if the issue is your model's complexity or your IT environment.

cleanmgr.exe) to delete Windows temporary files.%TEMP% (type this into File Explorer) and delete all files and folders older than 24 hours.D:\Moldflow_Temp).The most common cause is poor mesh quality, specifically high aspect ratio elements or overlapping elements.
Q: Is Error 99998 related to my graphics card? A: No. This is strictly a CPU/memory/disk I/O error. Your GPU has nothing to do with it.
Q: I have 128GB of RAM. Why am I still getting this error? A: Because the issue is likely the Windows path length (Solution 2) or a read-only .mfr file (Solution 4). RAM size is rarely the primary cause.
Q: Does Error 99998 corrupt my study file? A: It can. The solver terminates mid-write. Always run a “Save As” to a new study name after encountering this error to avoid file corruption.
Q: Can I ignore it and click “Continue”? A: No. The analysis stops immediately. There is no “Continue” option. You must fix the root cause.
Check *.mfr or *.out log in study folder for exact error before 99998.
Example log snippet:
ERROR 99998: Solver terminated - insufficient memory for matrix solver.
Before fixing the error, you must understand what the solver is trying to tell you.
Official Definition: Error 99998 is a generic “fatal error” code that the Moldflow solver throws when the internal memory management system fails to allocate a required buffer. The “Full” suffix typically indicates that a specific queue, log buffer, or disk cache has reached its maximum predefined size.
In non-technical terms: Moldflow asked your computer for permission to write data to a specific file (usually the .mfr result file or a temporary .tmp file). Your computer said “yes,” but when Moldflow tried to write the data, the buffer was already overflowing. The solver terminates to prevent data corruption.
