Dear meep users:
I tried the example program in C++ Tutorial but I got a segmentation
fault.
gdb result:
" Program received signal SIGSEGV, Segmentation fault.
0x08049dcd in meep::boundary_region::~boundary_region()"
I am a newbie here. Have you ever met this problem? What is the most
probable reason and how to handle it?
Thank you very much!
By the way, the example program :
#include <meep.hpp>
using namespace meep;
double eps(const vec &p) {
if (p.x() < 2 && p.y() < 3)
return 12.0;
return 1.0;
}
int main(int argc, char **argv) {
initialize mpi(argc, argv); // do this even for non-MPI Meep
double resolution = 20; // pixels per distance
volume v = vol2d(5,10, resolution); // 5x10 2d cell
structure s(v, eps, pml(1.0));
fields f(&s);
f.output_hdf5(Dielectric, v.surroundings());
double freq = 0.3, fwidth = 0.1;
gaussian_src_time src(freq, fwidth);
f.add_point_source(Ey, src, vec(1.1, 2.3));
while (f.time() < f.last_source_time()) {
f.step();
}
f.output_hdf5(Hz, v.surroundings());
return 0;
}
Sincerely,
Zhaoys
