Hello friends,
I am new on OpenFOAM and want to simulate a transient flow over a NACA0015 using pisoFoam solver. I want to emmulate a sinusoidal velocity at bc "jet" but I don't know if it is well defined. Apart I get an error from openfoam: /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v2006 | | \\ / A nd | Website: www.openfoam.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : _b45f8f6f58-20200629 OPENFOAM=2006 Arch : "LSB;label=32;scalar=64" Exec : pisoFoam Date : Jan 14 2021 Time : 20:56:05 Host : LAPTOP-KI5PL9IT PID : 649 I/O : uncollated Case : /home/agrande/OpenFOAM/OpenFOAM-v2006/run/muestra1 nProcs : 1 trapFpe: Floating point exception trapping enabled (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 5, maxFileModificationPolls 20) allowSystemOperations : Allowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 PISO: Operating solver in PISO mode Reading field p Reading field U Reading/calculating face flux field phi Selecting incompressible transport model Newtonian Selecting turbulence model type RAS Selecting RAS turbulence model SpalartAllmaras --> FOAM FATAL IO ERROR: Entry 'method' not found in dictionary "/home/agrande/OpenFOAM/OpenFOAM-v2006/run/muestra1/system/fvSchemes.wallDist" file: /home/agrande/OpenFOAM/OpenFOAM-v2006/run/muestra1/system/fvSchemes.wallDist From bool Foam::dictionary::readEntry(const Foam::word&, T&, Foam::keyType:ption, bool) const [with T = Foam::word] in file /home/pawan/OpenFOAM/OpenFOAM-v2006/src/OpenFOAM/lnInclude/dictionaryTemplates.C at line 334. FOAM exiting I don't know which is the error I am doing neither if the jet velocity is well defined. |

I would also start with a steady-state approach (i.e. simpleFoam) before diving into the transient case.
