Hello,

I'm new to icem maybe someone can give me a little help.
I try to mesh (hexa) a diagonal cylinder. I used blocking and rotated the block within which the the cylinder is 45 degrees. That block is a OGrid and i associated the edges from the OGrid to the cylinders curves(pictures).
The problem is if i read that mesh in Fluent (after translation in icem etc.) the cylinder is missing.
Maybe someone knows how to handle tis problem or a better way to mesh the cylnider
thx

can you attach the .tin?

Hi Far,

I already tried different blockin strategys but couldn't find a godd way to mesh the cylinder.

thanx for your help

[Far]

are you trying the simulate the tip effects as well, or just 3d cylinder due to nature of flow?

[FVH]

I'm trying to simulate heat transfer and CW

[FVH]

also tip effects

Meshing done,just attaching blocking file so you can idea about splitting and association.

Sory for quality have "less time" reached min ortho 0.7. rest you must do it yourself

Fantastic. I have improved some angle issues in blocking, but it is less than .00000001 % effort, originally put by nitinbansal184

Really great but how you have done the inclined cut in the vicinity of inclined cylinder(this has made the job simple for you)?

Recently i have done meshing on flat plate with angle of attack 15 vertically and tilted at some angle horizontally.......Used same concept here..

If I am not getting you wrong you mean to say that you have done the blocking of cylinder in vertical position and then tilted the blocking at the angle, is it so?

Thank you all very much for your answers!
I will be back on the PC on monday but probably i will have some more questions, if you don't mind!

[FVH]

Hi Nitinbansal and Far,

thank you very much it is really ineterssting how you approach this problem. Can you give me any advise how i should use blocking in the future? I know that it always depends on the current problem but mybe you have some basic advises.

Understand how to use the o-gird function
