I’ve had several problems with my code in 3D, and now one more is left.
If I just place spheres into the lattice (via the Domainfunctional) the code works fine (at least up to 265000 iteration steps).
But if I place my structures of interest into the lattice, it will crash sooner or later (20k to 60k steps so far).
Now what I’m wondering about is the error message :
[PC183:14967] *** Process received signal *** [PC183:14967] Signal: Segmentation fault (11) [PC183:14967] Signal code: Address not mapped (1) [PC183:14967] Failing at address: 0xbf0bb60c [PC183:14967] [ 0] [0xb77da410] [PC183:14967] [ 1] finderror02(_ZN3plb14BlockLattice3DIdNS_11descriptors21ForcedD3Q19DescriptorEE16collideAndStreamENS_5Box3DE+0x30e) [0x80ee19e] [PC183:14967] [ 2] finderror02(_ZN3plb19MultiBlockLattice3DIdNS_11descriptors21ForcedD3Q19DescriptorEE16collideAndStreamEv+0xe2) [0x80e64a2]
were a Segmentation fault usually is the result of moving out of the range of an array or something similar. So I don’t understand why this should happen after 20k or 60k steps, and not right at the beginning.
Or is this the MPI way telling me occoured somewhere ?
Any ideas/hints ?
