A lot of designers have been using tetra element meshing kind of “by default”…
When you see and hear everyone around you telling that automatic tetra meshing is the most convenient and easy way to get your model meshed, it’s tempting to just do that.
But in fact, automatic tetra meshing has always been kind of a marketing hype propagated by FEA software company to tell everyone how much they product is fast and easy to use.
I am not telling it is not good… I am telling there is better out there.
Now…if you are a real engineer here’s what I advise you.
Try to create manually a nice and smooth brick meshing and I promise that you will see the difference:
- In terms of computational efficiency
- In terms of accuracy
To show you how to actually do that, I decided to show you one of the simplest examples I could find…a valve stem.
So here’s the nice brick mesh we will try to get:
How did I do that, very simple… so simple that I decide to make a very short video to show you the actual process. You will not believe how much it is actually easy to create such a nice and smooth brick mesh.
BTW, I am using a software called midas NFX, but the same procedure is also reproducible easily with other software available on the market.
A nice and smooth brick meshing takes really not much effort to build and provide an incredible increase in both accuracy and performance.
Some additional notes:
- If the geometry cannot be easily broken into components for brick mesh, unfortunately, tetrahedral mesh is still the best acceptable way to fill a volume
- Some pieces of software provide also tetra-brick hybrid meshing, but this kind of meshing is not standard
