5 years agoInsert particles globally.
Luca Heltai [Thu, 21 Nov 2019 18:30:17 +0000 (19:30 +0100)]
Insert particles globally.

Create and insert a number of particles into the collection of
particles.
This function takes a list of positions and creates a set of particles

at these positions, which are then distributed and added to the local

particle collection of a procesor. Note that this function uses

GridTools::distributed_compute_point_locations. Consequently, it can

require intense communications between the processors.

5 years agoBreak postprocessing the velocity out of the function that computes errors.
Wolfgang Bangerth [Mon, 2 Dec 2019 22:57:30 +0000 (15:57 -0700)]
Break postprocessing the velocity out of the function that computes errors.

The step-61 program now has a separate function
'compute_postprocessed_velocity' that computes the velocity field as
a postprocessing step after computing the pressure variable. The
resulting velocity field is used in both computing errors and when
creating graphical output.

There is really no functional change, it just rearranges the code
and makes it a bit simpler to read. The only functional simplification
is that we don't compute the velocity at quadrature points from shape
function times coefficient, but use FEValues::get_function_values()
instead.


In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
