since i think there are missing BC, i tried these values and i got almost similar results as in the video: heated pipe inlet (1-6): velocity 0.001 m/s, temperature 400~450 K heated pipe outlet (1-6): temperature 400~450 K inlet: velocity 0.002 m/s, temperature 300 K outlet: temperature 300 K pipe wall, pipe wall shadow, wall fluid domain: material steel

for simplicity and to save the solution solving time, you can neglect the pipe wall thickness. If you want to simulate the real-life problem you can model it, no issue., but you will not get much more variations in result. Try in both cases.

Yes reverse flow affects the solution ,try to avoid the reverse flow warning , but if its still present after a lots of iterations, and your result coming approximately same then no need to worry about reverse flow.

not all solution need to be converged always , you can make the convergence very fast /delay by changing the convergence criteria. The iteration graph and results should be satisfactory .

Just ignore this warning, this generally comes if you have not assigned the domains as solid /liquid in the geometry modeling part (design modeler).This will not affect the result. The most important part is the assigning the solid /liquid domain in fluent cell zone . The error might you getting regarding failed mesh is due to the mesh restrictions if you are using a student version of ANSYS. If in your work ,no of elements are more than 5120000 then I will suggest to first reset the mesh and again mesh it with a large size cells so to get less elements.

Good question Omer, As per your query, you can also do like that by creating two sketches and then extrude. I have created it to illustrate the creation of geometry in a convenient manner. you can also export geometry created in any other CAD designing software into ANSYS. As you are a beginner I will suggest you to go through "Cornell university Ansys and fluent tutorials", and first start from 2D simulations, then after that proceed to 3D problems. So that you can understand the concept behind this clearly. You can also ask in our KZbin channel discussion page. Thank you

Check the flow model, whether its Inviscid or laminar or turbulent. if it is inviscid then change it to laminar/ turbulent. If this is not the problem then check the cell zone condition, and check whether the flow domain are assigned as fluid or not.

for solving heat exchange three models are available they are dual cell model ,macro model (grouped ungrouped) after turning on the energy equation u can see heat exchanger below radiation or check this linkwww.afs.enea.it/project/neptunius/docs/fluent/html/ug/node508.htm

what add frozen command do

[@AnsysTutor]

add frozen keeps the domain as a different entity (multiple parts), but in add material, the newly created domain becomes single entity (single part) with the previously created domain.

Ansys-Tutor thanks bro

[@farazahsan1530]

Hi , I have followed all the steps exactly as the video . But when I initialize the solution , an error message appears " Flow Boundary zone found adjacent to solid zone, This problem must be fixed before solution proceeds" Could you please tell me how to resolve this issue ?

[@AnsysTutor]

Please check the cell zone condition, you might have assigned the fluid domain as " Solid"

[@farazahsan1530]

Thanks a lot , problem solved
