Test run case error: Flux data #58

Hi
I'm having an issue while running the test case scenario. The test case I selected is ows papa. The problem is that even if I multiply the heat flux data with a large multiplier I am not getting any change in the output temperature. I am not able to identify the mistake. The only change I have made in the configuration file is the heat flux data file.
What might be the cause of the error and what should I do to correct the run?

look under

surface:
fluxes:
method: fairall # method to calculate fluxes from meteorological conditions [off=use prescribed fluxes, kondo=Kondo (1975), fairall=Fairall et al. (1996); default=off]

heat: # prescribed total heat flux (sensible, latent and net back-radiation) [W/m^2]

constant_value: 0.0 # value to use throughout the simulation [W/m^2; default=0.0]

constant_value: 0.0 # value to use throughout the simulation [Pa; default=0.0]

column: 2 # index of column to read from [default=1]

This is the configuration that I have done

and how does you heat flux file look?

It is a dat file

Hi sir,
The surface heat flux from the output file does changes for both cases ie., with normal flux as above and the one with the flux multiplied with 1000. But the range of the input and output flux data has a huge difference (in the range of about 10 to the power 3).
Even if the flux data has a change, the output temperature has no change.
