How can I get the global coordinate of Integrated Point

[Aquaman]

Dear all

What I'm looking for is the global coordinate of the this Integrated Point which the stress, strain, residual, and tangent are calculated based on.

I guess a command like in Abaqus UMAT: COORD(3)

But How I can get the X,Y,Z components in DEALII?

Thanks in advance,

Jacob

Dear Jacob,

You should have a look at step-8, for example. In assemble_system() some local material properties are computed by evaluating some functions at all cell quadrature points:

FEValues<dim> fe_values(fe, quadrature_formula, update_quadrature_points | …);

for (const auto &cell : dof_handler.active_cell_iterators())
{
  fe_values.reinit(cell);

  …

  lambda.value_list(fe_values.get_quadrature_points(), lambda_values);

}

So fe_values.get_quadrature_points() returns the real positions of the coordinates at the integration points.

Best,

Jean-Paul
