Hey, every time I run an example apart from the simple wing I get the following error:

signal (11): Segmentation fault
in expression starting at /home/nish/.julia/packages/FLOWUnsteady/MpOG2/examples/vahana/vahana.jl:376
unknown function (ip: 0x7fffed0735da)
Allocations: 6767744745 (Pool: 6767383817; Big: 360928); GC: 179
Segmentation fault (core dumped)

Sometimes, the system even crashes.

I have dual-booted Windows and Ubuntu 22 and I'm running flowunsteady on Ubuntu. I have a 24-core machine.

Is this a hardware issue? How do I fix this?
Thanks.

Segfaults are really hard to debug. I wonder if you're running out of memory.
Try reducing the discretization on the wings and props and reducing the number of timesteps. See if the segfault exists for a really coarse case.

Thank you for the quick reply.

This is a snip of htop running parallel to FLOWunsteady and the memory consumption is super low.

Edit: I have noticed something strange. I do not get this error for the simple wing and for ALL the other cases I get the error during the timesteps ~150-200.

Update: I set up FLOWUnsteady on WSL and I'm still getting the same error. Please find the attached error with a bigger message.

Is it possible to tell me if this is a hardware issue or a code issue? I have an I9-14900k 24-core machine.

Your workstation's specs should be fine for these cases to run fine.
I would check in htop if the memory goes above the limits when it's close to throwing the segfault.

Since the simple wing case works fine, I would try running it for a longer time and see if it throws a segfault when there's close to the number of particles in this simulation. Or simplify this case and see if it runs for longer timesteps. I'm still inclined to think some sort of memory limit is being hit by these simulations. Not sure why/how though.
I've had issues with memory limits imposed by Linux on the stack size sometimes. The command ulimit -s unlimited resolves those. Again, I'm not sure if that's the cause here.

We're in the process of phasing out the FMM package (FLOWExaFMM) for a native Julia one because it has given us a lot of trouble. So hopefully this issue will also be resolved with that switch.

Really odd. The stack trace points out that the error is on the C++ part of FLOWExaFMM. As @cibinjoseph mentions, my guess is that there is an issue with the amount of memory that the process is allow to use.

ERROR: Package CxxWrap errored during testing

@cibinjoseph The memory consumption does not shoot up at any point.
@EdoAlvarezR Since you indicated that the error might be in the C++ part I removed the package CxxWrap and added it back. Now I get this error.
Do you guys know how do I to fix this?

Thanks.

PS: Strange that I'm still able to run simulations with this error.
