I need to make a common module for mesh, many functions for elements are
shared.
Also, try to reduce the 'select type' statements, but I don't know
enough Fortran for it.
While testing the examples distributed with the code, a few errors were
found and fixed, mostly related with the K matrix in 1D geometry and
reading values from initial conditions for species.
Finalysing first step of performance improvement focusing on reducing
iteration CPU time by improving calculation of basic element functions,
which took a lot of the CPU time
I noticed that phy2logquad had a lot of overhead. Trying to reducing it
by simplifying calls to fPsi, dPsi and such.
The function for fPsi has been made so no memory is allocated and works
under the assumption that the input array has the right size (1:numNodes)
Merging branches and fixing a number of important issues:
- Initial particles were not being assigned to the list of particles.
- List of particles was being erased every iteration, even if species
was not pushed.
These caused issues with the calculation of collisions when a species
was frozen.
Now, things should work properly. All particles are properly added to
the volume list and the list is erased ONLY if the species has been
updated.
I hope that collisions are now properly accounted for per species pair.
Now the number of collisions is calculated per species pair. This allows
that the randomly particles selected for collisions do not have
collisions assigned.
First implementation of Electromagnetic pusher.
Some testing is still required.
Documentation needs to be upgraded to match the changes in this branch.
Implementation of the 0D grid to test collisional processes.
An OMP_LOCK was added to the nodes to properly write perform the
scattering (it is weird that multiple threads work in the same node at
the same time, but in 0D happens everytime).
Added a new case to test the 0D geometry.
User Manual updated with the new options.
easy to use a file from a previous run without processing it into a
plain text file.
Although the previous method presented some updates for 1D small cases,
this is quite easy to do with any type of simulations and, in the
future, with different mesh formats.
Unification of boundary conditions into one file.
Some changes to input file for reference cases. This should have been
done in another branch but I wanto to commit to save progress and I
don't want to deal with tswitching branches right now, I'm very busy
watching Futurama.
Possibility to input initial species distributions (density, velocity
and temperature) via an input file for each species.
New moduleRandom includes function to generate random numbers in
different ways (still uses) the implicit RANDOM_NUMBER().
A boundary condition for each species must be indicated in the case
file.
This opens the door to use boundary conditions with different parameters
(for example, a wall temperature, coefficients for reflection or
absorption...)
The examples included with the code have been updated accordently.
into account (as in 1D Cartesian case).
The 1D Cathode example case has been modified, having now 2 input files:
- inputCart.json: Used for Cartesian coordinates
- inputRad.json: Used for Radial coordinates
Pusher is a Boris pusher but without z direction.
