Hello everyone!
Can I create "Vector<double> x(n)", to store data values from a Tensor<1,
dim> or Point<dim>, for physical coordinate after mesh/grid?
I can create "Point<dim> x", to store data values from a Tensor<1, dim>, it
works thru like:
Point<dim> x;
for (const unsigned int i: fe_values.dof_indices())) {
x = cell->vertex(i);
}
std::cout << x << std::endl;
But how to use "Point<dim> x" for computing with other variables together?
Like, I cannot implement "x * fe_values.shape_value(i, q_index)". However,
it does not work thru if I tried like this:
std::vector<Point<1>> x;
for (const unsigned int i: fe_values.dof_indices())) {
x[i] = cell->vertex(i);
}
std::cout << x[i] << std::endl;
It gives:
make[3]: *** [CMakeFiles/run.dir/build.make:77: CMakeFiles/run]
Segmentation fault
make[2]: *** [CMakeFiles/MakeFile2:237: CMakeFiles/run.dir/all] Error 2
make[1]: *** [CMakeFiles/MakeFile2:244: CMakeFiles/run.dir/rule] Error 2
make: *** [Makefile:202: run] Error 2
How to store data values from Tensor<1, dim>, into a created
"Vector<double> x(n)", for computing with other variables together?
Thank you so much!
Judy
