Hi everyone, well i'm developing an investigation of pasive snow removal on the BPEFM chilean antartic base and i'm getting used to openfoam.

Actually I could run a 3D simulation with simpleFoam and RANS turbulence model but i have some problems with validating my results. I mean that the results i get i don't know if they are fine or not. Second and most important is that I tried to understand the physic meaning of the parameters on the "0" folder. This initial conditions such as epsilon, nut, nuTilda, R (I know that p is preassure and U y velocity) but although I don't understand the meaning of the values given i've just copied from another simulation but I need to modify parameters such as air viscosity, resistant, velocity column.

If someone know where can I learn this things I'll be very greatfull. (i'm from chile so if you have the answer in spanish much better).

Hi everyone, i'm having another type of problems now, so PLEASE HELP!, first:

The domain is a box and i need that the bottom face to be a wall, the left face to be the "inlet" of a 30 m/s wind and the right face to be like the outlet, the front,back and top faces i need them to be like a "open sky" boundary. I'm trying to simulate an outdoor experiment and i don't know what type o BC should I use.
The important thing is that i don't want the faces to affect the vortex generated by the delta wing.

Finally I don't know what parameters should appear on the 0 folder for simpleFoam, RANS, Spalart Allmaras config.
