I have isolated the error to minimum (not-) working example: The error
occurs
when Point and Boost functions are used at once in a dealii program.
I have observed that in the Point class there is usage of some boost
functions,
could it be that there is clash with that boost version and the below
combing
from the boost include file?
usingBoostindealii.cc :
#include <boost/math/special_functions/spherical_harmonic.hpp>
#include <iostream>
#include <vector>
#include <cmath>
#include <deal.II/grid/tria.h>
#include <deal.II/grid/grid_generator.h>
#include <deal.II/grid/tria_accessor.h>
#include <deal.II/grid/tria_iterator.h>
#include <deal.II/fe/fe_values.h>
#include <deal.II/fe/fe_nothing.h>
#include <deal.II/base/quadrature_lib.h>
#include <deal.II/base/timer.h>
using namespace dealii;
int main()
{
Point<3> evalPoint(1.0, 2.0, 0.0);
Point<3> evalPoint2(1.0, 1.0, 1.0);
std::vector<double> atomPos{0.0, 0.0, 0.0};
std::cout << evalPoint.distance_square(evalPoint2) << '\n'; // comment this
to test the below too
double sphericalHarmonicVal{};
double r{}, theta{}, phi{};
// std::vector<double> relativeEvalPoint(3, 0.0);
// // *** even with the below there is same error ***
// for (int i = 0; i < 3; ++i)
// {
// relativeEvalPoint[i] = evalPoint(i) - atomPos[i];
// // relativeEvalPoint[i] = evalPoint[i] - atomPos[i];
// }
sphericalHarmonicVal = boost::math::spherical_harmonic_i(0, 0, 0.0, 0.0);
std::cout << sphericalHarmonicVal << '\n';
return 0;
}
