Possibility of FlexSim crashing

Hi,

FlexSim may crash in the middle of running a large model on my PC. However, this phenomenon is not reproducible.

After running a large model on my PC, FlexSim's CPU usage stays above 20% until it crashes. My PC has 4 cores, so that core is always above 80% utilization.

I'm using 'Fast Forward' to run, so I don't think the graphics affect it. The memory seems to be relatively free, but the CPU load seems to be high. I suspect the CPU is underpowered, is it possible that FlexSim crashes because the CPU usage is too high?

Thanks in advance.

FlexSim 22.0.16

Only if you exceed the thermal limit for some reason - most CPUs throttle back the clock speed to manage this. You'd expect each FlexSim vcore to be 80-100% utilized while running.

Does your model repeat correctly each time you run it? Does it run to completion if you are not fast forwarding?
