Dear @rajesh.kanna,

Welcome to the Netfabb forum!

As the error message advises, please review the thermal and mechanical output files to troubleshoot the issue. They are plaintext, human-readable files that will contain information on what went wrong. Without this review, troubleshooting the issue it will be difficult or even impossible.

Also, please make sure your system meets or exceeds the system requirements.

Kindly find the result file for your reference.

Report say " restart cache\project_1234_thermal.in\3ED450C5"

[steffen_anders_adsk]

Both OUT files state:

---

Autodesk AM Process Simulation has not been able to acquire a license to run, please contact Autodesk

---

This is a licensing issue.

Try the following:

1. Open a command line, and run the command pan without arguments.
2. This should prompt a new Autodesk login dialog to refresh the login for the solver.
3. The command line window can then be closed.

Once performed, future attempts to solve from the Netfabb Local Simulation GUI should be successful again.

Enter the name of the input file w/o extensions. What should i enter?

[steffen_anders_adsk]

Nothing. As instructed earlier, you can close the command prompt without further action and continue working with through the Netfabb Local Simulation GUI again.

[rajesh.kanna]

Error remains the same. Any other solutions.

I will need more detailed information to investigate, including what user and license is involved, which is not a matter for a public forum. I invite the user to come forward through a customer support case.

[rajesh.kanna]

I came to know that you are already following up the customer with case number - [removed]

Kindly Help here to solve.

Mod edit: Removed detail.

I faced the same error regarding the thermal and mechanical outputs. Can you check my project file, please?

[mohammad_hazori]

I have exactly the same problem. For the simulation of the SLM process, I downloaded Netfabb 2025.1. After defining the machine, parameters, and supports, I started the simulation. Then Simulation Utility LT for Netfabb 2025.1 opened. I defined the parameters again. During meshing, I kept getting this error. Can anyone help? Thanks!

[jorge_crespoUACEB]

I am facing the same problem, even with just meshing

Hello,

For Simulation Utility LT 2025 and 2025.1,

Download and unpack the ZIP archive attached to this message.

Place the contents AdskIdentitySDK.dll and libcurl.dll at <Netfabb installation folder>\SIM\Solver\bin\

Then try again.

Kind regards,

Steffen
