I am trying to simulate a plate being heated with a heating torch. The flame is to be simulated as gaussian distributed heat flux over a circular area. I could do it with constant heat flux over a square patch. Can anyone help with writing the macro? Also, for applying film coefficient which depends on temperature, how do can I get the table (I could assign a table, but I cant understand how the system takes the table as it is not specified anywhere which column stands for which i.e. temperature or coefficient)?
