Dear anon_a,


Thank you very much for your suggestions.


The number density I used in dsmcInitialiseDict is 1.836E+25, so the mean free path is 100nm. The smallest distance is 1000nm...

Hey anon_a,


Sorry for my late reply, I was on vacation last week.


I’m trying to simulate a closed box, where one of the walls is heated. After some time, the entire box should reach a...

Hey,


I have run one case with Kn 0.1 and one with Kn 1, where all other conditions were kept the same, such as wall interaction model (Maxwell), collision model (VariableHardSphere) and number...

Hey anon_a,


Thank you very much for your help. I will run a few simulations with different Kn numbers and boundary conditions. As soon as I have any results, I will get back to you.

Hey anon_a,
I did some more simulations with your comments in mind. The cell size is 0.01 mm^2 (see picture) where the inlet, outlet, and sides are defined as walls and boundaryT at the inlet is...

Hey anon_a,


I just checked all of the temperature settings and they are as follows:


In the 0-folder, for boundaryT: one wall is set at 700 K, all other wall are at 300 K. The...

Thank you very much for your answers! I’m not so familiar with C++ so I only looked in the calculated files for a specific time step (e.g. internalT). Here, the dimension is [1 2 -2 0 0 0 0], which...

Hi all,

I'm also starting to use the dsmcFoam solver for my OpenFOAM simulations and to get more familiar with the solver, I set up an easy case:

2-D rectangle (1x10 mm) with simple Grading...
