width in curve meshing
In this thread http://www.cfd-online.com/Forums/ans...hing-icem.html, Simon has given a tip of making boundary layer around 2d object.
He used width to make boundary layer.
But what is "width"?:confused:
I can only find "Tetra width", as seen in the picture.
And also why he didn't use Number of Layers to make that boundary layer?
sadjad.s: May be by setting tetra width simon was able to generate tetra mesh with some layers packed into boundary layer. he also said that prism in 2d failed due to the way geometry is assembled. Finally he shown the way to work with HEXA.
I think i got the answer via try and error.
In 2d, there is no difference between "No. of Layers" and "Tetra width".
As you see in the first picture, i used No. of layers of 10 to make boundary layer. It did it successfully.
In the next try, i used Tetra width to make 8 layers:
And if you determine both parameters, mesher will ignore Tetra width for 2d cases:
Did you turn on blayer2d?
I tried both options
1. no of layers and
2. tetra width.
both have same effect, but no of layers overrule tetra width.
Actually in 2d there is no need to include prism section.
All is done by curve mesh setup.
