Insufficient Memory Answered

Dear Support,

I am currently running a 2D model which runs fine for my initial settings. I set the system up in the Designer Mode and then switch to Analyst mode to tweak the output results.

However, if I increase the analysis time from 5µs to 25µs the system reports back the "Insufficient memory allocation" error. Changing the memory allocation via the mem command has no effect. The downloaded input file automatically overwrites the mem command to the default settings. I also tried to run withtout the mem command, same result: the downloaded input file again has the default mem command written in the first line.

It seems I am missing an important point regarding the memory managment. Could you please help me to resolve the issue?

    Hi there,

    If you go to the Options (cog in the top right corner) you can set the numerical and character memory in Solver Settings.

  • Dear Chloe,

    thank you for your advise. Unfortunately the problem persists even if I ramp up the allocated memory considerably  (up to 15 Gig) for just a slight increase in simulation time (5 to 6 µs, 5 works, 6 does not).

    The same issue occurs for another problem I try to run. Also happens while  trying to run it on a machine of a colleague.

    So we are kinda stuck at the moment. Is there another possibility that could cause this issue?

    Best regards,

  • Hi Mike,


    Your model may be too large to run on your local machine. Have you tried estimating this on the cloud1? If you share your file via your preferred cloud sharing file service I can take a look for you.

    Best Regards,
