Hi everyone

My name is Agnelo

I'm new to the CFD world. I'm need help from you. I'm having trouble to fix the wall distance in meshing CFX, what i mean is: i need to create a mesh with tetra elements in tube with trapezoidal cross section to measure the pressure drop later, but the mesh in Ansys CFX is automatic, it generates a mesh for al the body but i just want a the inner part of the model to have this tetra elements and the outter part is for the wall distance to calculate the y plus, for several runs.

I dont if you can help me, but i need this for a school project. please help me.
I uploaded as well a picture of the desired mesh so you can understand what i mean.

Thanks

Agnelo
