Hi guys,

 

During my last simulation I was struggling with the problem below:

 

executeAlgo_c : Execution failed.
Failed execution
ZMLONG: No more space avalaible in dynamic numerical memory
ZMLONG: Available size : 189 MiB.
ZMLONG: Required size : 297 MiB.
ZMLONG: Assigned size : 1024 MiB.
ZMLONG: Please increase memory up to at least : 1321 MiB.

 

This has appeared when I started to mesh the domain. Do you know which could be the issue and how should I fix it? Thank you

    Hi

    Probably you lauch a solving too much complex and FLUX is asking you to increase the memory for meet the high request of hardware resorurces.

    For fixed it you have too option:

    -Change the memory dedicated to FLUX. For doing this go to Flux first page when you open it, in the bottom left corner there is the Option button, click on it and in the memory menu, move the cursor to increase the memory used

    -Use a larger mesh in your model, so the memory request will be less

    I had the very same problem. This suggestion helped. Thank you very much, I had to save, close completely (model window not the supervisor) and re-open the model for new memory settings to apply.

    Hi,

    When you get this error message you need:

    • Close the Flux project

    • Increase the allocated memory

    • Open again the Flux project

    Best regards.
