Hi guys,



I want to generate a mixed mesh for a combustion reactor. The detailed configuration of the reactor is attached in the attachment. A .tin file is also attached.
For the eight small nozzles, I want to use tetra and for the rest part (long cylinder), I want to use hexa mesh.

How can I achieve this? I got problems when I tried to merge mesh on the interfaces since the interface the nozzles share with the reactor cylinder only occupies a small portion of the cross section of the cylinder, I don't know how to deal with this.

Any comment is welcomed.


Thank you so much.
