Autodesk Moldflow Error 99998 Full 🆕

Sometimes a previous Moldflow solver didn’t close properly.

Moldflow uses a default temp folder on your C: drive. If C: is a small SSD, it will fill up quickly.

Solution:

Real-time antivirus scanners (McAfee, Norton, Windows Defender) sometimes lock the .tmp files Moldflow creates in the %TEMP% folder. When the solver tries to write to a locked buffer, it sees it as “full” and throws error 99998.

Autodesk Moldflow Error 99998 generally indicates that the solver cannot access a required license. This can occur if all licenses are currently in use, the license has expired, or the software cannot communicate with the license server.  Common Causes 

License Availability: All AMI_STANDARD, PREMIUM, or ULTIMATE seats are occupied.

Server Communication: The license server is down, or firewall ports (e.g., TCP 44100/44200 for 2023) are blocked.

Configuration Issues: The licpath.lic file contains the wrong server name or IP address.

Installation Errors: An incorrect product key was used, or the License Configuration tool hasn't been run.

System Time: There is a significant time/date discrepancy between the client and the server.  Step-by-Step Troubleshooting  Check License Status Open LMTools on your server.

Navigate to the Server Status tab and click Perform Status Inquiry.

Verify if your solver licenses (MFIA, MFIB, or MFIP) are listed and if any seats are available. Clear Rogue Processes

If licenses appear "in use" but no jobs are running, open Task Manager.

End any instances of flow.exe, cool.exe, warp.exe, or mhb3d.exe that are at 0% CPU. Restart the adskscm (Simulation Compute Manager) service. Run License Configuration Utility

Go to Windows Start Menu > Autodesk Moldflow Insight 202x > License Configuration 202x.

Ensure the "Network License" is selected and the server hostname is correct (use port@server if using a custom port). Set Environment Variables

If requests are timing out, create a system variable named FLEXLM_TIMEOUT with a value of 10000000 (10 million) to give the server more time to respond.

Ensure ADSKFLEX_LICENSE_FILE is correctly set in your system variables. Verify Firewall Ports

Ensure the following TCP ports are open based on your version: 2023: 44100, 44200 2021: 43100, 43200 2017-2019: 43911, 42911, 43921

Are you running this analysis on a local machine or a remote solver? 

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. autodesk moldflow error 99998 full

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)?

Did this start happening after a recent update or a new installation?

In Autodesk Moldflow, Error 99998 is a general licensing failure that indicates the solver (Insight) cannot find or check out a valid license. While the error log might occasionally include terms like "full," it is rarely a disk space issue; instead, it typically means the license pool is full (all seats are in use) or the solver cannot reach the server. Common Causes & Fixes

License Seats are Full: If your organization has a limited number of seats, Error 99998 often occurs because all available licenses for Moldflow Insight are currently being used by other analyses or users.

Fix: Wait for other jobs to finish or check the License Manager (LMTools) to see who is using the seats.

Solver vs. UI Mismatch: You may have a license for Synergy (the user interface) but not for Insight (the solver). Error 99998 specifically triggers when the solver starts and fails to find its own separate license.

Incorrect License Configuration: The Simulation Compute Manager (SCM) or the solver might be looking at the wrong license server.

Fix: Run the License Configuration Tool (found in the Moldflow Insight folder in the Start menu) and re-enter your server hostname and license level (Standard, Premium, or Ultimate).

Network/Firewall Blocks: A firewall might be preventing the solver from communicating with the license server on ports 2080 or 27000-27009.

Expired License: Verify in your Autodesk Account that your subscription has not expired. If you suspect Disk Space ("Full")

If the error truly relates to a "full" drive rather than a full license pool:

Clear Temporary Files: Moldflow generates massive temporary files. Check the temporary directory defined in your Simulation Compute Manager settings and ensure that drive has at least 50–100GB of free space.

Reset Job Manager: Sometimes the database for the job manager becomes bloated or corrupted. You can follow the guide to reset the Simulation Job Manager database to clear stuck jobs. Solved: ** ERROR 99998 ** - Autodesk Community

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.

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.

Autodesk Moldflow Error 99998 is one of the most dreaded errors in injection molding simulation. It is a "fatal" error that causes the solver to crash immediately, often without generating a results file.

Unlike specific warnings (like "short shot" or "air traps"), Error 99998 is a generic crash code indicating that the solver encountered an unexpected mathematical condition (like dividing by zero) or a memory violation that it could not handle.

Here is a full review of the causes, diagnostic steps, and solutions for Moldflow Error 99998.

Moldflow uses RAM first, but for large 3D meshes, it spills over into the Windows page file (virtual memory). If your page file is set to a fixed size (e.g., 16GB) and Moldflow needs 32GB, the allocation fails, and you get Error 99998.

Because 99998 is a generic crash code, there is rarely a single "fix." However, the error almost always stems from one of three categories:

In Moldflow, Error 99998 is a general “solver failed” error.
“Full” often means the analysis stopped because of a full disk, full memory, or full license error — or the solver output exceeded a limit.
