Multiple inert gas EquationSet
|
| |
I have a shock tube model which I'd like to convert to use two
distinct inert gases (driver/driven). Looking in stdlib/equations, I
found ShockBubbleEquations which looked promising. However, the
machinery required by BCG doesn't seem to be present, so the latter
chokes on its call with a 'BCG under construction' message. (ie, no... more »

Porous Wall Boundary Condition
|
| |
Hi all,
Matei and I wanting to simulate his porous wall detonation
experiments.
Does anyone know of or have any ideas for a boundary condition which
mimics
the "loss" effects or non-perfect reflectivity of a porous wall?
My idea was to include a non-reactive layer of complient (i.e. a gas
of some non-infinite density)... more »

time integration at a fixed grid location
|
| |
I would like to know how one can do a time-integration at a fixed
location on the grid, in a multi-grid situation.
For example, right now I have a piece of auxiliary code where i
compute a new field variable NEW at each time step, from which I want
its time integral W[7]. For a time integration, I simply cumulate the... more »

recording data along an internal boundary defined by a levelset
|
| |
I hope someone can help me with this one.
In a simulation with an internally defined boundary, defined using the
levelset function PSI, I would like to record some variables along a
line of constant PSI.
Is there any direct way I can do that? So far, I have used the
"probe" command, while manually parametrizing a sequence of (x,y)... more »

Trouble to startup a supersonic flow over a triangle
|
| |
I've been trying to run simulations that consist of a supersonic
freestream flowing over a triangular obstacle. The problem I'm facing
most of the time is to startup the simulation, especially when the
flow turns around sharp corners. To provide an example, I uploaded a
script called "Wedge", which generates a NaN at the 15th phase. Does... more »

Supersonic wedge into combustible gas
|
| |
I'm a PhD student at McGill University, and I intend to use AMRITA to
investigate different flowfields around a projectile travelling at
hypersonic velocities into a combustible gas.
So far I've been able to run a simulation with a sphere as the
projectile. Here is a part of the script specifying the boundary... more »

finite rate Euler
|
| |
There is a FiniteRateEulerEquations within amr_sol which was never quite finished. I would like to use such a package and would like to know whether anyone out there has made any headway in this direction or has any plans to do it, whether from scratch or starting from what has been done in the existing code.... more »

plotting a subset of the domain
|
| |
Hi,
I am having some trouble plotting a subset of my 2D computational
domain. I am trying the command "clip to ..." and "clip on ..." as
per the example in the help manual. However, when running the example
script, both "clip to" and "clip on" yield the same result. I
expected the "clip on" to rescale to the pagesize.... more »

missing directory when installing v3.03
|
| |
When installing v3.03, there is an error when trying
$ amrmake src3p::perl
requiring a manual creation of the directory
$AMRITA/bin/perl
Creation of the directory fixes the problem.
