hello everyone
I want too see wall shear stress contours in tecplot.I have got the answers from openfoam and I have calculated wall shear stresses in openfoam so I expect to be able to see these contours when I load data from openfoam however I cant find any tab or menu which shows wall shear stressed that also have read from openfoam. is there any idea? |

Hello 1988,
I know this post is old but I have exactly the same problem. Did you solve your problem and if yes, do you remember how? Maybe someone else faced this problem too. Cheers! |

you should add a code like this to your 0 folder (based on your BCs) Code:
/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.2.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volVectorField; location "0"; object wallShearStress; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform (0 0 0); boundaryField { outlet { type calculated; value uniform (0 0 0); } inlet { type calculated; value uniform (0 0 0); } defaultFaces { type calculated; value uniform (0 0 0); } } // ************************************************************************* // Code:
wallShearStress +you will have three WSS in tecplot for each direction and by adding this formula you can calculate WSS magnitude (Go to Data > Alter > Specify Equations and enter the following equation: ) Code:
{WSS Magnitude} = sqrt({WSSx}**2+{WSSy}**2+{WSSz}**2) |

Hello 1988,
thanks for your reply. Unfortunately, I already concluded my calculations. I used the command "wallShearStress" to postprocess the WSS in OpenFoam. Now I have a new file for each time step containing the calculated wall shear stresses, but Tecplot isn't able to regognize them... Is there no other way to import the WSS in tecplot afterwards? |

hah I found averaged WSS contours by paraView (it was easy) as I had not found any way in tecplot to calculate these aounts. |

Yes, I did it in paraView too by choosing wallShearStress in the Variables-List and the desired surface.

do you know how can i define the axial of a curved tube as the x ? یعنی محور وای بشه مقادیر تنش برشی و محور ایکس بشه محور لوله خمیده Last edited by navid.a; September 19, 2016 at 13:50. |

Hello 1988,
I have a problem regarding the WSS conversion from OpenFOAM to Tecplot. Actually, I can obtain WSS results but when I convert the results to Tecplot, then WSS values are seen to be zero, although they are not. I don't know how to resolve that issue, could you please help me if you have any idea? |

Any solutions? It doesn't work by the way mentioned above.
