How to mesh cylinder and box combination?

Posted by mohammad fereshtehpour at December 15. 2012

Dear Friends

Hi

For my thesis I need to mesh the geometry including box and cylinder. I want to know if there is  way to use hexahedral mesh for this case?

My geometry is attached.

Thanks in advance

Hello, Mohammad,

Maybe you can use the pattern visible in the enclosed picture to create a blocking mesh.

Best regards,

William

Dear St Michael

Thanks for your reply.

But I really don't know how to apply  my model to this script. Where should I change in that.? As you can see in the picture my model is 3D but the model in script is 2d.

Sorry for such a these questions actually I'm beginner.

Dear William I've done exactly what I learnt from you and St Michael. But I have an error :

"Non-quadrangular mesh faces are not allowed on sides of a composite block"

The picture is attached

Could you please tell me what the problem is and what should I do to solve that?

Best Wishes

I have a question about viscous layer . As you know when we want to define viscouse layer we have to specify faces without layer .Here we have alot of faces to specify. Is there any way to specify faces with layers instead of them.?
