The temperature profile: The temperature gradient (representing heat flux) profile: The bounded region or the so-called ROI is 0.005<r<140 m and physical width of infinite element in the r-direction is 10 m. As you can see, the temperature and its gradient are both continuous at the...

Here are the results that I get: Either I am missing something on how I should implement this Infinite Element in Comsol, or I am mistaken to believe that Infinite element works for this scenario. Let me elaborate more on the problem: A fluid with high temperature is being injected into a...

Thanks again for your prompt reply. Please consider this geometry At the inner BC, a fluid at constant temp is injected, and far at the infinity, the boundary condition is another constant temperature (lower than that at the inner BC). Also, the temp at initial condition is the same as that at...

Hi, thanks for your reply. Yup, I have checked them, and I think I am doing it right for the problem that I am considering. I have a question; to numerically solve an infinite region problem, one way is to draw a very lengthy region, right? And, now one functionality of infinite elements domain...

Hello folks, I want to simulate a 2D heat transfer process in the subsurface on a region which is infinite on the r-direction. So, as you know, the very basic way to model this is to draw a geometry that is very long in the r direction. I have done this, and the results that I obtain is correct...
