Hello everyone! Thank you for your attention. I'm working on an unstructed mesh with ICEM, the model is a Cone-Cylinder-Flare model with a lateral sonic nozzle. Currently only half of the geometry is modeled because of the symmetry characteristics. However, after some tries, i got a mesh without prism on the symmetry, shown as below in figure1.

Interestingly, the prism of this mesh was only missed on the symmetry. The cut plane through the axis of the nozzle is posted below in figure2.

I have tried to change the parameters of Prism Meshing, while there is no efficient progress in solving this problem.

Is there anyone can help with this problem? Thanks a lot!!
