*** stack smashing detected ***

[sean-mcsherry]

Hello,

I am receiving a stack smashing detected error.

I am using the scuff-scatter tool on a geometry that is a simple cylindrical fiber, which is infinitely extended in the x-direction. I need to make the mesh small enough such that the scattering cross section is accurate for small wavelengths (0.2 - 2 um). However, if the mesh is small and I apply periodic boundary conditions, I receive the stack smashing detected error.

Is this an error specific to my computer? (i.e. I do not have enough memory for the calculation) Or is a problem with my geometry/simulation? It occurs when the incoming plane wave is polarized in the x-direction, the same direction that the fiber is "infinitely" extended.

I have attached in image of a representative geometry that I am modeling.

Here is another geometry that it will occur for:

Hi, could you please provide the exact input files and command line arguments that gives you the error?

And BTW no, this is not a problem with your computer, "stack smashing" points to an error that is almost certainly a bug in the software. It might be easy to fix it for me if you help me to reproduce the bug.

If you are using extended geometry, it's quite likely that this error has the same source as #220; if it's the case, #222 should fix it for you. You can try my fork, which currently has some more bugfixes compared to the upstream, https://github.com/texnokrates/scuff-em
