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.
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 ?
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)?
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

The details shared in this video cannot be found easily. Thank you for your clear explanations.
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
Thanks for the sessions was very useful. How would you change the water to a pressurised constant velocity flow
can you organize a session for the training of UDF,UDM and UDS ......... thanks
Ultra awesome tutorial
I love these sessions

THANK YOU
thank you. this info is excellent.
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

Can fluent solve bioheat transfer model and electromagnetic model simultaneously as console multiphysics ?
Could u please make a model of double pipe heat exchanger using pcm for solidification/melting
how to add cul-orthotropic thermal conductivity in fluent?
Can you attach the geometry of the case between 19 minutes to 31 minutes in the video ?
plz make the video on melting and solidification model
Is the recent iris xe graphics with the 11th gen i5 16gb ram compatible and sufficient with ansys for medium 3d simulations?
