OpenFOAM ERROR with CfdOF Solver

Post by cfdee »

Hi everybody

I want to simulate a laval-nozzle with the CfdOF addon.

In a first step I prefer a 2D simulation to save calculation time and get a first impression of the behaviour. Now I'm at the point where I could make a mesh which looks not too bad in my opinion (2D, cfMesh, 0.8mm base size, Surface Mesh refinement, rel. element size 0.1, 3 boundary layers with expansion ratio 1.2). Two pitcures can be found in the attachement just to get an impression of the model (attached files for more detailes):

After defining the boundary conditions (Inlet on the left--> Uniform Velocity, Outlet on the right --> Static pressure, Symmetry condition at the bottom, Rest of faces as walls, please see attached files) i try to solve the Problem. Now I have the problem that I get the following error:

Code: Select all

-> FOAM FATAL IO ERROR: 
Cannot find patchField entry for cyclic _master
Is your field uptodate with split cyclics?
Run foamUpgradeCyclics to convert mesh and fields to split cyclics.

file: C:/Users/SIMON~1.MUE/AppData/Local/Temp/casexy/0/p.boundaryField from line 26 to line 58.

    From function void Foam::GeometricField<Type, PatchField, GeoMesh>::Boundary::readField(const Foam::DimensionedField<TypeR, GeoMesh>&, const Foam::dictionary&) [with Type = double; PatchField = Foam::fvPatchField; GeoMesh = Foam::volMesh]
    in file X:/OpenFOAM-5.x/src/OpenFOAM/fields/GeometricFields/GeometricField/GeometricBoundaryField.C at line 180.

FOAM exiting
I found that when I delete the following part from the file "C:\Users\cfdee.cfdee\AppData\Local\Temp\casexy\system\createPatchDict" the error does not occur anymore but a different error occurs.

deleted part:

Code: Select all

    {
        name _master;
        patchInfo
        {
            type cyclic;
            matchTolerance 1e-04;
            neighbourPatch _slave;
        }

        constructFrom patches;
        patches (None);
    }

    {
        name _slave;
        patchInfo
        {
            type cyclic;
            matchTolerance 1e-04;
            neighbourPatch _master;
        }

        constructFrom patches;
        patches ( None);
    }


Next error:

Bug fixed - thank you.

Fixed direction of inlet velocity and pressure initialisation value to get the case to run.

Thank you for the quick response oliveroxtoby. :D :D . Simulatin is running 8-)
