示例1: error_total
// function used to combine the contributions from solution components to the total error
double error_total( double (*efn)(MeshFunction*, MeshFunction*, RefMap*, RefMap*),
double (*nfn)(MeshFunction*, RefMap*),
Hermes::vector<Solution*>& slns1,
Hermes::vector<Solution*>& slns2 )
{
double error = 0.0, norm = 0.0;
std::vector<Solution*>::iterator it1, it2;
for (it1=slns1.begin(), it2=slns2.begin(); it1 < slns1.end(); it1++, it2++) {
assert(it2 < slns2.end());
error += sqr(calc_abs_error(efn, *it1, *it2));
if (nfn) norm += sqr(calc_norm(nfn, *it2));
}
/* Alternatively, without iterators:
double error = 0.0, norm = 0.0;
for (int i=0; i < slns1.size(); i++) {
error += sqr(calc_abs_error(efn, slns1[i], slns2[i]));
if (nfn) norm += sqr(calc_norm(nfn, slns2[i]));
}
*/
return (nfn ? sqrt(error/norm) : sqrt(error));
}示例2: add_boundary_conditions
void EssentialBCs::add_boundary_conditions(Hermes::vector<EssentialBoundaryCondition *> boundary_conditions) {
for(Hermes::vector<EssentialBoundaryCondition *>::iterator it = boundary_conditions.begin(); it != boundary_conditions.end(); it++)
all.push_back(*it);
markers.clear();
create_marker_cache();
};示例3:
void NeighborSearch<Scalar>::Transformations::apply_on(const Hermes::vector<Transformable*>& tr) const
{
for(Hermes::vector<Transformable*>::const_iterator it = tr.begin(); it != tr.end(); ++it)
for(unsigned int i = 0; i < num_levels; i++)
(*it)->push_transform(transf[i]);
