Basic COMSOL heat transfer in solids

[@hussainalhoushan]

Thank you for this informative video, I would like to ask, Is it possible to model a Transient HT problem for a an Insulated tank that contains aggregate held in 100 c and see the temperature of the aggregate after 24 hours, in other words what would be the temperature of the aggregate after 24 hours if it was preheated and sent to the tank at 100 C. I appreciate highly if you could suggest something or tip sth in this regards. which boundary conditions may be used in such case, and how to model the aggregate? Thank you in Advance

Thank for this tutorial which analyzes the problem of thermal conductivity. if I'm using a cube model that contains a sphere, can you tell me how I can add thermal periodic conditions in the case of a micro model? or I can only use the two thermal conditions that you add in this problem !!!

Thank you so much for watching video #saad bouta
you can add thermal periodic boundary conditions ... you can get temperature change between two boundary conditions over a period of time by adding CUT LINE 3D from results .
for other queries please mail me ...

if I understand, I use only the PBC on one direction, while the other directions I add nothing!, see this image: ibb.co/kuE3Tp

hello sir i had used the periodic condition for heat transfer
but there were some comsol warnings while performing, but the best way you can use two different temperature boundary condtions for both the sides as i shown in the above video ..
please check it: ibb.co/eAXtd0
I may understand the problem in a better way if you could explain the problem statement

[@mechatron5683]

In PBC the condition is (delta T) = T (source) - T (destination)
T (source) is the temperature of overall initial temperature of entire geometry
T (destination) is the targeted boundary where the temperature is low at the value entered in (delta T) ...
check this out ibb.co/hRDSML

My problem is the study of effective thermal conductivity behavior of a biphasic composite material. You can understand this picture: ibb.co/edq2O0
I did not understand the difference: (delta T) = T (source) - T (destination), or T (source) is the temperature of entire geometry. If possible I will send you an email to clarify the problem.

thank you your video is very helpful

Please could you tell me how can I use dU/dy=0, d^2V/dy^2=0 (the second derivative of velocity)
and d^2T/dy^2(the second derivative of temperature) on Comsol

Thank you so much

[@pankajjagdale2005]

But there all material shows same distribution of heat

Hallo,
Give an example of computer simulation programming to simulate heat transfer on a media axis using comsol!🙏

Hey thank you for video can ı have ur mail and ı can ask about my comsol project
