For the tutorial including the fins with surrounding air domain, I believe the air density is not constant to have the natural convection. For this, the 'ideal gas law' option was probably selected for air under the Materials section.
is there an option in put a file into Fluent that has data showing how much heat is made over time? Like an Excel file with numbers for how much heat is made (in watts per cubic meter) at different times (in seconds)?
At 16:56 you have not explained the key issue. When using option 2. or 3. How is heat transfer in the wall normall direction handled, when the problem is transient? Does it actually integrate the transient heat conduction diff. equation in the wall normal direction using some virtual numerical 1D discretization (in the wall normal direction), or perhaps, it is using analytics valid only for steady heat transfer (transmissive heat flux between 2 fluids through a wall), i.e. the heat flux is equal the temperature difference over sum of resistances. That approach would be approximative for a time dependendent problem since there is thermal inertial in the wall. In other words, what exactly does FLUENT do with the given information on wall thickes and the wall material properties, please ?
Hi there I am going to simulate a fire in tunnel by using fluent ansys and I have question about the density of air inside the tunnel how should i define it is it incompressible ideal gas or ideal gas the problem is transient grateful yousef

You save my degree. Thankss
Hi, have u found any source file about the tutorial. I'm working on it for a project.
Thanks for this session. Helped me a lot.
Thank you for your support on these videos. Glad it helped! KETIV | Marco
Ultra awesome tutorial
I love these sessions
thank you. this info is excellent.

THANK YOU
can you organize a session for the training of UDF,UDM and UDS ......... thanks
Thanks for the sessions was very useful. How would you change the water to a pressurised constant velocity flow
Can fluent solve bioheat transfer model and electromagnetic model simultaneously as console multiphysics ?
Hi there
I am going to simulate a fire in tunnel by using fluent ansys and I have question
about the density of air inside the tunnel how should i define it is it incompressible ideal gas or ideal gas
the problem is transient
grateful
yousef
Good video.
I have a case like this but with outer copper cylinder I tried to define it as heat source but it didn't affect the interior water
how to add cul-orthotropic thermal conductivity in fluent?
plz make the video on melting and solidification model
Can you attach the geometry of the case between 19 minutes to 31 minutes in the video ?
Could u please make a model of double pipe heat exchanger using pcm for solidification/melting
Hi, what if my heat source comes from a fluid domain? Can i specify the heat source for fluid domain as well? Thank you
Is the recent iris xe graphics with the 11th gen i5 16gb ram compatible and sufficient with ansys for medium 3d simulations?

How do you assign the emissivity to the shadow wall?
How do we add thermal contact resistance?
Hi Imran, you can reach out to us at support@ketiv.com for more help!
Can u please soon post about creating a mesh interface

You're welcome, thank you for stopping by!
Hello Miss Snigdha , i need your mail id regarding conduction of training course for my students, can you please share..
Hi there, you can reach out to support@KETIV.com to get more information on training sessions!
Can you show how you create the contours and plots in post processing?
Take a look at this link for your answer: th-cam.com/video/SsORGWCg1ss/w-d-xo.html
hi , can you please help me to solve a helical coil heat exchanger fluent validation.
please pass your contact
Attach geometry..... To the video.. Pleas3
