Hello,

I am trying to generate a hex-mesh for a u-tube contained inside a rectangle in ICEM. The problem statement is: fluid flows within the pipe which exchanges heat energy with the surroundings.

If it was only a U-tube, I know the blocking strategy and how to mesh. But I am facing difficulty when it is contained inside the rectangular box. If possible, I do not want to mesh parts separately and merge them later.

I wonder if anyone has gone through similar problem before or does have an idea about its blocking strategy.

Hello Sajjan,

If you already know how to do the meshing of the U-tube alone (simple Ogrid sweep) you can then add a second O-grid around the first one (select all the blocks in ICEM and then tick the "Around blocks" option). Then do some additional slicing / association to the outer rectangle and it should do the trick.

Have fun
