Hi everyone,nWhen I try to run a varFDTD simulation I get the next error:nUntil yesterday everything worked just fine, but suddenly it showed me this error.nI tried to reinstall Lumerical but it didn't help. Also, when I run a simulation on FDTD it works well.nMy memorey requirements are normal:nDoes anyone know what might be the problem? I have tried to look it up on the internet but couldn't find anything.nThanks a lot,nEita

ethank,

Can you try to save the simulation file on a location on your local drive where you have write access. Do not save to One Drive. You can copy the simulation file later after running the simulation job. Also a directory or folder that does not have special characters - only English text/characters. Let me know if this helps.

Hi Lito,

Thank you very much for the response.

Unfortunately I tried to do what you said but it didn'y help. I got the same error.

But now I found the reason for the error. The reason was the integration with matlab. I have integrated matlab via this window:

When I inactivated the integration, everything returned to normal. I don't know why.

Thanks for the help anyway!

Array,
That is odd that the Matlab integration is affecting you simulation job. Unless Matlab is running in your machine. Glad to hear that you resolved the issue.

Hi Lito,

I met the same problem. After I activated the matlab API, the simulation cannot run any more. It shows the Job 1717 error. What can I do to solve the problem?

Because I still need the matlab api to use

Thanks a lot,

Polang

Polang,

Sorry do you mean that the simulation works if you disable or set "inactive" the Matlab integration in Lumerical? Try removing the "FDTD Solutions.ini" file from your machine. Open a Windows command prompt and Run;

del %AppData%Lumerical"FDTD Solutions.ini"

Also try running with Local Computer as your job launching preset. See this post for details.

Best,

Lito

I have tried this but still doesn't work. I am getting the same error in JobManager.

Rabi4_, did you try to unset the Matlab integration (inactive) in the Lumerical CAD? Did you try running using Local Computer as the Job launching preset? Paste a screenshot of the error message here when you run using Local Computer as the job launching preset.
