Hello all,

I want to apply heat flux [W/m^2]-time [s] data (the DAT file) as my transient boundary condition in COMSOL. How can I realize it?

Thanks a lot!

time [s] heat flux [W m^-2]

Hi

you can make an interpolation functions (DEFINITIONS ... node) then load your file and then in the postprocessing you might compare ina table write out gloal variables ...

Good luck
