Default Looking for a simple way to mesh my sample

Hi,

I am trying to mesh a plate with some regular square holes in the center of the plate width along the plate length. To generate a regular grid, I split the plate out of holes into some rectangular regions with either length or width equal to the size of the square. Now the problem is that since the side of the plate is connected to another geometry, if I want to mesh my whole geometry with regular grid, I have to extend these splits to the boundary of my geometry. Finally, my meshing domain becomes a large number of small rectangulars. It definitely is not a good way. I wonder if there is any other way to mesh my geometry using GAMBIT without splitting it to the small domains.

Any advice will be greatly appreciated.

Cheers Winnie

Dear Winnie:

If i am understanding your problem correctly; you have circulat plate with square holes inside. I think, using multiblock meshing is the best for your problem. Assume, a circle around square holes and mesh inside this circle using map scheme. (Split the circle first). Now split the outer circle and grade, then mesh the donut surface.

Best Regards Mehdi Ghoddosy

Hi; You can use hybrid mesh scheme.

Mehdi and rawin,

Thanks a lot!

Mehdi, your understanding was right. But my problem is quite more complex. I have a number of holes on a rectangular plate. Then if I use multiblock mesh, I need to seperate the whole domain into lots of small region. this will definitely bring lots of work when defining the boundary conditions. Can I have any method to mesh the domain out of the holes as one volume?

Rawin, I hope to generate regular meshes, since my geometry is quite regular.

Thanks again. Hope to hear more opinions from you.

Cheers Winnie

I'g go for the sizing functions I guess (not having seen the geometry)

Mesh the sides of the holes first Then apply a sizing function with the sides as sources and attached to the plate. And then mesh the plate using a paver (quad or tri).

Hope this helps, cheers,

Laika, still orbiting

Laika, thank you so much for your answer.

I will try and see if it works.

Thanks again. Winnie
