How can I get average heat flow through a surface in a thermal analysis?

      1. If there is a temperature/convection boundary condition on the surface in your model, you can probe the “Reaction: at the corresponding boundary condition to get the heat rate through the particular surface. 2. If there isn’t any boundary condition, the following APDL commands need to be copied into a command snippet inserted in the “Solution” branch. Here, “my_sele1” is a named selection of a surface through which total heat rate is to be computed. Commands: resume /post1 set,last cmsel,s,my_sele1 !select nodes on surface on which the heat flux valus are to e integrated to find the total heat rate esln !select the corresponding elements forming the surface fsum !sums the nodal force and moment contributions of elements *get,my_heat_tot,fsum,0,item,heat !retrieves the total heat flow allsel,all !select everything again
