Split blocks based on curves

Dear all,
I am trying to mesh a blunt delta (see image "BluntDelta.PNG") for a hypersonic flight simulation. Since it is flying at 0 degrees, I can take advantage of 2 symmetries (XY and XZ planes). I have to mesh it using ICEM and I have already drawn the curves that define all the blocks and projected them to the other surfaces (see images "BluntDelta_surfaces.PNG" and "BluntDelta_all.PNG") in order to make sure that all the blocks have 6 faces (hexahedral mesh). I am not very experience with ICEM, I only did one project and the split method was screen select because the geometry wasn't very complex. However in this case I have to make many splits with complex shapes and I would like to know if I can split blocks based on curves or if i can extrude them by selecting the bounding edges or points. Thank you in advance! |

Hi Captian,
This is likely not what you want to read, but please do the hexa tutorials. They teach some basic concepts on how to create blockings in ICEM. The preferred method in ICEM is to start with a single block, and cut it down into smaller blocks, reshape them, and delete unnecessary parts, etc. A more advanced, but not straight-forward is to create hexa elements manually (unstructured mesh section in ICEM), and use the created unstructured mesh as input to reconstruct a blocking (i don't remember the exact name, something like file>import blocking > from unstructured). However this method is somewhat error prone, and only works, if you can create the hexa mesh perfectly. Nevertheless, having all the curves, and points already present, this might be a your way to go, since you seem to understand the concept of hexa blocking, too. Best, Sebastian |
