Default Switching to ICEM from GAMBIT

Hello everyone,

I'm trying to switch to ICEM, from Gambit in which I have a lot of experience in. In contrast, I have just started using ICEM, so I have one strait-forward question in my opinion:

In Gambit, it was possible to create a structured 3D mesh in this way:
-> create 2D geometry (points -> lines -> faces)
-> create 2D mesh (edge mesh -> face mesh)
-> extrude 2D geometry (with mesh) to 3D

So in case you had structured mesh in 2D you get a nice structured 3D mesh. I would like to do the same in ICEM.

I have a geometry with lots volumes(in Gambit) and would like to avoid assigning blocks to every point/line/etc.

Is it possible to assign blocks in 2D and then extrude everything (like in Gambit)?

tl;dr: Is it possible to extrude 2D geometry together with 2D blocks, so no further assignment of blocks (in 3D) is necessary?

Thank you for reading and have a nice day,
- miro

it seems to be possible. Anyway, I have another question:

Is it possible to add blocks to existing part without overwriting the blocks that are already in that part? For example:
I have 3 blocks and I want to create another: adding by surface overwrites existing 3 blocks and I only have one. Changing part name seems to have very little effect.

Thank you very much for your time.

I always split the blocks to "create" new blocks which i then could properly assign and delete the excess. i'm not sure if this applies to your case or not..

hey miro..

this thread might be of some help to you..

How to extrude 2D Mesh in ICEM CFD?

i would like to add some information

if you want a 3D mesh try creating a 3D block from the start. It might look a bit complicated but you will get the hang of it pretty quickly..

Blocks cannot be extruded. only mesh can be extruded (as far as i know)
