getting (0 0 0) wallGradU value when i m probing wallGradU at some points
Dear friends my simulation is flow over a flat plate using LES in of210 and wants to find out wallGradU at some point wall (within 1st cell near to wall). First i have extracted wallGradU field for domain and then by using probeLocations option i m extracting wallGradU at required point locations but getting (0,0,0) value and my all points are within fisrt cell height.....plzzzhelp me on this...am i missing some data extraction???
(Direct wallShearStress option is not working for LES model so i m going to find out first dU/dY and then wall Shear Sterss by rho*nu*dU/dy)..)
Thanks in advance
I have a very similar problem, I am simulating a flow over a flat plate with interFoam (laminar) and I want wallGradU but it is zero everywhere.
Did you resolve your problem?
Did you instead calculated dU/dy yourself, and if yes how?
Thank you very much for your help.
