Hi, I 'am writing some UDFs for specifying some thermal boundary conditions under transient case (for example ,heat loss to ambiant, evaporation,....).However , these conditions are changing with time -we use mostlty meterological data (ambiant temperature,sky tem humidity...)witch are presented under tabular form at fixed intervals(every Dt hours). Please can you telle me what is the best procedure to read these data?

Thank you very much. Please advice me.
