Sometimes I do things right, then I change them thinking my old self was
an idiot and then they break.
The positive point: the solutions end up being better.
I should've commited before, but I wanted to make things compile.
The big change is that I've added a global time step so the parameter
does not need to be passed in each function. This is useful as we are
moving towards using time profiles for boundary conditions and injection
of particles (not in this branch, but in the future and the procedure
will be quite similar)
The correction in the node volume is no longer needed as now things are
being calculated right with the last change.
Still, at some point I should review the calculation of the node volume
in 2DCyl.
Basically things do not work. I've added a correction to the node volume
in the axis which gives okays results but still this is not perfect. I
need to find a better way to do things.
Also, I've noticed that the density changes with the size of the cells,
which should not happen! I'vw to check this issue.
So now each edge has the same number of particles and the weight of each
particle is calculated based on the surface of each edge compared to the
total one.
Only in 2DCyl, still to extend to other geometries.
Not perfect constant density, but the issue might be the node volume.
Fixed an issue with random integer numbers.
Cylindrical coordinates are not perfect yet:
- Box (cylinder) with initial constant density loses particles at r =
0
- Injection density still low in r = 0
I have tested all geometries and cases and all seem to work perfectly
with .vtu meshes.
Input and output works great, starting from a previous case also works.
Everything I was able to test is okay.
Still, what I want to do is to change a few things in the output (e.g.,
change OUTPUT prefix to Step) and try to improve reading gmsh meshes
to make them more compact as vtu is now.
For some reason the connectivity for collision meshes was not being
properly assigned.
Also, the first subroutine to read information from .vtu files as
initial states has been added.
It is currently giving wrong results.
First complete implementation of .vtu format.
Still a lot of things to improve but right now fpakc can read a vtu mesh
and write the output in vtu.
Still to test:
Multiple geometries.
Double mesh.
Moving forward making vtu an independent format.
Now fpakc can generate nodes and edges from vtu input.
Next step is cells.
Some minor corrections in gmsh2 format to unify statements.
The reading of meshes needs a good overhaul.
Testing all geometries with vtu is gonna be fun...
