block with a hole

nandiganavishal · April 17, 2013, 01:22

Hello Foamers,

I would like to create the following geometry in openfoam.

A small circular hole is drilled through a block (cuboid in shape). Please let me know how to create such a geometry in openfoam.

Thanks

Vishal

There is an example of how to do this in the user guide. You just have to extend it from 1/4 to the full block. Shouldn't bee difficult.

Thanks, Anton for the reply. Yes, this geometry is doable. What I wanted to create is the following geometry that is attached with this thread. A cylindrical hole is drilled through three membranes (two thick membranes and a thin membrane in the center). The membrane is then connected to two reservoirs on either side. I would like to know if there is a general code or format to create any geometry without having to define the vertices manually. Please let me know !!

Thanks

Regards,
Vishal

Greetings to all!

@Vishal: Try SwiftBlock: http://openfoamwiki.net/index.php/Contrib/SwiftBlock - this way you can create a "blockMeshDict" interactively.

Best regards,
Bruno

Thanks, Bruno. I would take a look at it.
