Upon setting the simulation to transient, I realized I had to switch my heat source from the uniform heat to a boundary condition. I switched to the power boundary condition and set the value of the power equal to that of the heat source power, and selected the same solid for the boundary, however the temperature I recorded with my monitor as well as the power flux on a separate debugging monitor were different for the uniform source and the power boundary condition. I am just interested in knowing what the difference is between the source and the boundary, and also why there is this discrepancy in temperature?<\/p>\n<p>Thank you!<\/p>\n","protected":false},"template":"","class_list":["post-343263","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello,I am currently running a lumerical heat simulation for a thermo optic modulator and was attempting to use the transient simulation to get an idea for the response time.
