Brick Solid Meshing

[Anonymous]

Hello,

First off, I am trying to teach myself FEA, so please excuse my ignorance.

I am trying to solid mesh a model with brick elements, and I have been stuck on one part for approximately 2 hours. it is a piece of u channel that is about 8 inches long, with no complex geometry.  I am running an i7 processor and 8 gb RAM.  Is this a normal amount of time for such a small part?

I am ultimately trying to run a frequency response simulation.  Are there specific settings I should apply for the brick meshing?

Thanks in advance for the help

Hi Mike,

did you import the geometry from a CAD program?

May you should check, if the geometry does not have discrete parts, or parts with excessive small radius.

If you use brick elements und you want several layers in the thickness of the profile, this will bring an excessive amount of parts for thin walled profiles, here you should go for a midplane discretization.

hi boris,

I imported the geometry from autocad inventor, and I dont think there are any excessivly small radii.

A few of the parts are about 1/16" thick, is this an appropriate time to use the midplane mesh?

Thanks for the help

Hi,

I think the ratio is ok for both meshing tyapes..

May you look here:

You could try the setting Bricks and wedges (layered mesh of thin parts): if you prefer the solid mesh in favour of the midplane mesh.
