I have been working on a mesh for almost 1 month and can´t find a good one. I don´t know what I have to do. I searched on youtube. I searched on manual´s user. I really don´t know. How can I do this mesh? (I took a print of the current mesh I did.) I´m sorry about my english, I´m from Brazil.
If someone could help me and have patience because I´m really unskilful about icem mesh. thank you

it is very simple topology.

search forum you will get very good threads, specially by Simon

Sorry to bother you, but how I find Simon ?
The problem is that my mesh is not matching in the junction of the cylinders.

upload files, i will try to correct it.

At first I got a good quality mesh, but then I exported it to the fluent and simulated it for the energy and flow. In the result the fluid isn´t flowing from the semicylinder to the bigger cylinder (it is a natural convection problem). Then I changed the geometry, to let the fluid flow into the bigger cylinder, but the mesh is not getting a good quality. I did the mesh by blocking.
If you can help me, I´m really really thankful.

blocking file is missing

This might help you. Do you have interface between bulb and long pipe?

at interface

woooow my God, you did it! So nice! Thank you so much!!

This is a part of a evacuated solar tube collector. The long pipe is half of the tube of the solar collector, where the water flows in to be heated. The bulb is part of the tank. The water flows from the tank to the long pipe, the water heats then by natural convection comes back to the tank.

I think it does not have interface because it is the same fluid flowing and because there is a mass transfer between the tank and the long pipe. Is this right? because I can´t say if I know for real what means a interface (I will look for more information about this). Sorry, I'm very new to it.

I can’t thank you enough for everything you’ve done.

I told you it is very simple. Just15 minutes...
