Dear Obinichi,

There are many ways to do this type of mesh, this is one that I consider easy to

undestand the process.

Start from a 2D surface block as shown in the Figure. Select the options and the

surface.

In the Block Menu, you must subdivide the edges as you think better, according to

your case.

You can copy a edge parameters to its neighbors edges, fill each one. The

spacements and laws are from your taste.

Select Pre-mesh to preview.

It needs an O-grid.

Select the o-grid and a good off set according to your case

Again, subdivide the new edge. Choose a properly spacement according to your Y+

Select Pre-mesh and generate an unstructured mesh as is shown in the Figures

In the mesh menu select Extrude Mesh. Select the surface elements. An d in the

part names you can set as default, or rename each part. My curve path was the

axial curve.

Chosse a good number of layers to capture the curvature. The result is shown in

the Figures.

My release is 12.1 there are better tools in the new releases. This is a very simple

example. The geometry would must be subdivided in minor segments, because in

the ICEM the geometric elements are parametric, and the curves have a normal,

torsion and tangent vectors that driven the swept direction , and some distortions

can happen.

A sequence of 3D blocks extruded is also possible and probably the better choice,

but it is need more knowledge. But is feasible.

I suggest to see:
