Hi everyone,
I was trying to get the yPlus field in the backwardFacingStep2D tutotial on OpenFOAM. I modified the controlDict and add in "functions" this part: yPlusThen i run simpleFoam -postProcess -func yPlusbut i have only the min, max and average value for each times step. My question is: How can i get, in a specific time step, a file with the values of yPlus along (for example) the bottom wall? Thanks in advance, Bartholomew |

the first one (in controlDict) should produce yPlus field at a given writeInterval. didn't you get it?

Hi,
thank you for your reply. Yes it does. I resolved today the problem: in order to plot the value of y+ along the x-direction i had to take columns from the respective files in the timeInterval (Cx and yPlus) and put them in a common .dat file. I think this is the easiest way to do it. Bartholomew |

Hi,
- try to use `patchEdge` sampledSet for sampling yPlus on patches, if necessary? - maybe using `nearWallFields` function object could also be interesting? at least you have solved the main problem - which is good ![]()

Hi Bartolomeo,
I have done the procedure that you have written in controlDict functions. But I got core dump error. Do you have any idea? ************************************************** ******************************* From function const Type& Foam: ![]() in file /home/ubuntu/OpenFOAM/OpenFOAM-6/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 193.
