Hi Folks!

hope someone is able to help me...

I've got an 2D airfoil which should have a hexa-mesh at the complete surrounding boundry. lets say for approx. 5 layers.

around that, my mesh should be the less exact tetra-mesh for the surrounding space.

if it's not really clear, check out following link... it's actually EXACTLY my problem!

so... what I wanted to do is to block the airfoil and generate an O-Grid around these blocks. then I deleted all the external and internal block (copied to VORFN) so that the rest of my blocks would only be my O-Grid which should be associated with my airfoil spline. when I press on "pre-mesh" it shows me a few layers and thats it.

how do I generate a "normal" grid, as used in tetra?

and then .... how do I create a treta mesh which connects to my hexa mesh?

thanks dudes!

what is shown in the picture is not the hexa layers, they are prism layers followed by the tetra mesh. to create a prism layer, first you have to create the tet mesh and then define the prism layers. there is a tutorial for creating prism layer in ICEM, check it out

with regards jeevan kumar

U can use cfx meshing to create the tetra mesh (with prism mesh) and not the icem cfd!

I am stuck where exactly icem-noob is stuck.

I am trying to simulate the flow over a cylinder.

I got the o-grid mesh around the cylinder but how do I get tri meshes in the surrounding region and also how do I connect the tri & o-grid meshes ???

Any kind of help is appreciated.
