    Total heat flux or temperature gradient of plate in welding

    Hi. Is it possible to find the total temperature gradient of plate after welding? i want to find entropy generation of plate versus time and then integrating on total time,finding total entropy of plate. entropy is (heat flux/temp.) but abaqus output is nodal or element temp. or heat flux. what...
