What steps will reproduce the problem?
1. I tried to do the simulation with channel flow procedure(phisical
size:4×pi,2,2*pi grid size:128*129*84) .In the end, I can get the
ux001-ux030,uy001-uy030,uz001-uz030,pp001-pp030,vort001-vort030 etc binary data
file.
2. Then I use the pathline.f90(in the attach files),to translate the binary
data to ascii data,in order that I can watch the data with Tecplot
3. But the results show that It isn't my ideal expectation output. The result
isn't perfect! I don't know whether there are something wrong in my post
processing?
What is the expected output? What do you see instead?
My expected output : more clear flow field structure information is shown than the LES/DES.
What I saw is the coarse output without enough flow field message.
What version of the product are you using? On what operating system?
Incompact3d under UbuntuKylin13.10

Not an issue!!!
Is there a 2D version of Incompact, i'm planning to do some simulations in a
periodic 2D box

What steps will reproduce the problem?
1. I perform the experiment with the channel flow just according to the
official code
2. And then I tried to modify the boundary condition(0 2 0) to (2 2 0),so that
I can add the inflow and outflow condition.I did the modify because I found
that if nclx==2(incompact3d.f90),then the inflow/outflow is added in the
simulation.
3. Oohs,sucks! I tried to track the result with times going on, but the
divergence U move to NaN. Later on,I check the boundary conditions of the
computational domain in the 《high order compact schemes ...》:"The use of
the Dirichlet conditions on the velocity(for no-slip or open conditions)need to
be defined acoording to the time advancement procedure".
4. So,I vim the schemes.f90,but I don't know how to modify it,can someone give
me some ideas?
-------------------------------------------------------
What is the expected output? What do you see instead?
My expected output is the turbulent development process,rather than the Tollmien–Schlichting wave(http://en.wikipedia.org/wiki/Tollmien%E2%80%93Schlichting_wave) with the parallel flow assumption.
