HEAT error code 0xc0000005


    • Sarah Skoff

      Hi everyone,


      We are trying to simulate a plasmonic structure with DGTD and analyse its thermal response to Joule heating simiarly to the example in the Application Gallery (Photothermal heating in plasmonic nanostructures (DGTD) – Ansys Optics)

      However, if we import the absorbed optical power and scale it to a factor which is appropiate for the structure the HEAT simulation throws up an error with code: 0xc0000005 and the additional message: 

      C:\Program Files\Lumerical\v231\bin\thermal-engine-msmpi.exe

      As I understand that error is linked to a access violation in Windows. Has anyone of you any idea how to fix that?

      Running Win 11 Pro (Version 22H2) and Lumerical 2023 R1.2 to which I updated to this week.

      Additionally, the same error is raised if we try to run the simulation at our Server which runs an older 2022 R2.4 version of DGTD/HEAT on a Windows Server 2016 operating system.



      Thank you very much in advance.

      Try to save the simulation/project files on the local drive of the computer running the simulation, not on a network or cloud drive (like OneDrive, DropBox, etc) or a folder that has to sync to a different drive.
