Hi Everyone ,
I am working on chtMultiRegionSimpeFoam solver for simulating a fin tube heat exchanger, I wish to calculate the value of Nusselt number so i have been refering to several threads and came up with an idea to make changes to the wallGradU to calculate gradient of T at the wall patch. But whenever i use this utility i get Code:
Create time Create mesh for time = 0 Time = 0 Reading T Calculating wallGradT Time = 1600 No T Time = 1700 No T Time = 1800 No T Time = 1900 No T Time = 2000 No T End Please help me with this. Referred link: http://www.cfd-online.com/Forums/ope...timesteps.html |

I suppose the problem is because the "T" is in separate folder that is say for 2000 iterations : instead of 2000->T ,i have 2000->regions->T
So can anyone direct me how can i make changes to the path for utility wallGradT. pleaseeeeeee help |
