Exporting shear stress data
I want to obtain the values for shear stress. I´ve tried all available options of exporting data in the CFX Solver, with no success. There is another way to get this?
Thanks everybody. |
Re: Exporting shear stress data
Hi Severo,
I you are looking for the wall shear stress there is a variable for that. Exporting wall shear stress should be easy. I have just noticed (to my surprise) that there is no preset variable for the full 3D shear stress field. It looks like in this case you will have to create the variable. Create an expression in Post to evaluate it from the velocity gradient. Glenn |
Re: Exporting shear stress data
Is velocity gradient availabe as a solved variable? Under what name?
Thanks |

Hi Drona,
It is accessible in CFX-Post. Press the "..." button next to the variable selector. Glenn |

Glenn,
Thanks. So the shear stress for a turbulent flow is: Tau (x,y,z) = Turbulent/effective viscosity * Velocity gradient(x,y,z) ???? Drona |
