I am trying to obtain values of temperature in non-isothermal lid driven cavity problem using openFoam. What I try to do is changing lid's velocity and obtain the temperature values at certain points for those different velocities. I can solve the problem and get the results using paraView but I want to use probes at those points and get them as separate files. I can do that for p and U bot not T. After I generated probes, the code only generates p and U values although I also added T for probe code. Can anyone suggest something to create a new field variable and capture it using probes?
