بسم الله الرحمن الرحيم

What did you mean by tetrahedral cells around the trailing edge ?

If you mean the rear upper and lower small connectors illustrated on the attached figure

I advice you to split the full domain with a vertical line or extrude only the upper and lower structured part and select the BC to be constant x ,which achieves the splitting between quadrilateral and tetrahedral elements.

else if you mean TE point ,when using T-Rex
selecting full layer = 0 --> multiple normal will starting from TE
selecting full layer = 1 --> single normal will starting from TE

Try all and show what is the highest minimum included angle

All praise is due to Allah

best wishes

Thank you for the reply.

The issue is ,when I create a block using the farfield domains and the wing's walls, then try to initialize the block using T-REX, it doesn't work, I can see the extrusion working, till everything around the wing is red, then an error message says that the entity couldn't be initilized.
