Delineate Boundary condition

mderosca · July 9, 2012, 07:02

Hi to all,

I want to delineate my Boundary spicified velocity condition in x cordinates.

My Mesh Block has 2 meters wide and my inlet condition is only in 0.20 meters.

How can I delineate the Boundary condition in X direction?!

Already solutionated with multiblock geometry.

Use components or baffles to block off the other 1.8m of the upstream boundary that are not open to flow.

Thanks for the reply.

After some time working with the code I've arrived to several solutions. The option of block the entry seems to be the better.

Hi dear mderosca
can you explain details.

With multi-blocks you can define a Mesh-block to determinate the inlet of fluid and another to determinate the Domain region. This procedure presents problems asociated to multi-blocks geometries (see in Flow 3D user's web).

And using components or baffles to block the entry (as said JBurnham) you can use only one mesh block with elements (solid elements) to block the parts of the domain. Is easier and faster than multi-block model.
