One method is to use a beta option in WB: In WB, Tools –> Options –> Mechanical –> Scroll down and check “Thermal Variation (beta)” beta option. Restart WB for this option to take effect. In the details of the surface body, you can select “Thermal Variation (beta)” option and also use an option for Convection to be applied on Top or Bot of the face. Because you use different temperatures at top and bottom surfaces, you will need to extract temperature with user defined results. TTOP is temperature at top surface. TBOT is temperature at bottom surface.<\/p>\n","protected":false},"template":"","class_list":["post-165582","topic","type-topic","status-publish","hentry","topic-tag-2019-r3","topic-tag-mechanical","topic-tag-static","topic-tag-structural-and-thermal","topic-tag-structural-mechanics"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
