I have a steady state 2D axisymmetric model where i have 2 different bodies, a first body is a rectangular region which stands for a copper coil, the second body is a plastic core in which the coil is embedded. You can imagine these two regions to be to modeled as one rectangle inside the other. Then, as the model is set up to be 2D axisymmetric, we will have a sort of ring, made by an internal copper ring which is embedded in a plastic ring. In the copper body i set up an internal heat generation according to the Joule losses I have in the coil, then i have some convection coefficient between the plastic core and the environment.<\/p>\n<p>Let&#8217;s say i have 10W of Joule losses. Then I have to divide these 10W by the entire volume of copper and put the number in the form of W\/mm3 in the internal heat generation condition of the 2D rectangular region that models the copper ring.<\/p>\n<p>What i don&#8217;t understand is that in the results i plot the heat fluxes, which are in the form of W\/mm2, and if I sum all the products of the heat flux times the correspondent surface i don&#8217;t get the initial 10W heat source i set. Same thing happens with the reaction probes. This is strange as the study is steady state and the energy balance must be guaranteed<\/p>\n<p>&nbsp;<\/p>\n<p>thanks to everyone open to help ????<\/p>\n","protected":false},"template":"","class_list":["post-347060","topic","type-topic","status-closed","hentry","topic-tag-2d-axisymmetric","topic-tag-ansys-thermal-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hi Everyone,I&#039;m doing a pretty easy thermal study.
