Re: Compressible flow inlet not matching boundary conditions
Hi: I created a really simple test case of a 0.2m cubed domain with periodic y and z boundaries to show you what I mean. See attached cube.tar.gz Inlet boundary conditions: Imposed inlet V = 500 m/s (normal to inlet) P = 500 000.0 Pa T = 1200.0 K Outlet boundary conditions: Subsonic Outlet P = 250 0...

Re: Compressible flow inlet not matching boundary conditions
Has anyone looked into this or noticed his behaviour?

Steady state compressible flow
I noticed that the combination of steady-state and compressible is not possible in the 3.3.2 GUI. Is there an example available of how to do this using user scripts?

Re: Tutorial about the coupling simulation with SYRTHES
Thanks for the suggestion. I gave it a try but I still get a segmentation fault when I run regardless of which domain partition option I choose. I am running with 1 processor so I am not sure it uses any domain partitioning.

Compressible flow inlet not matching boundary conditions
I have a 2D compressible flow model of three stationary airfoils (one stage of a turbine). I have periodic boundaries on the top/bottom (Y+ to Y-), symmetry Z+/Z- of the fluid domain, imposed inlet with velocity/temperature/pressure set, and subsonic outlet with pressure defined. Even long after sta...

Re: Tutorial about the coupling simulation with SYRTHES
Hi there: I tried with the stack size you recommend and even tried adding an order of magnitude. The results are the same: ./valgrind --main-stacksize=100000000 --leak-check=full ./syrthes -d tmp.data --log /home/stefan/test/3disks2D/solid/listing_syrthes ==57075== Memcheck, a memory error detector ...

Boundary Condition Help
Hello experts: I have an airfoil test case (with validated data from instrumentation) that I would like to use to validate Code_Saturne. The given information is as follows: INLET: - Total Temperature - Total Pressure - Velocity magnitude (with angle) Outlet: - Total Temperature (same as inlet total...

Variable viscosity mathematical expression editor
I have a compressible model and would like to define a simple power law for the viscosity as a function of the temperature ratio (Tk/Trefk). When I go into the user expression, TempK is not one of the options available for Predefined Symbols. In fact, even the examples tab has examples which use Tem...

Re: Error Running a Simulation of a Cylinder
Hello:
My mistake, I didn't read the error message over carefully. I agree in this instance that the error message is fairly clear. Perhaps we can also output also the line number and input file name that caused the error?

gamma, Cv, and Cp
Hello: With other CFD solvers, we are normally able to input two of the three: gamma (Cp/Cv), isobaric specific heat Cp, and/or isochoric specific heat Cv. In the GUI I only see the ability to input Cp. 1) Feature request: Can the GUI be updated to allow gamma and/or Cv? 2) Can someone provide an ex...
