Hi, I'm cofan.

I changed my model, The parts that went wrong were unchanged. Now ICEM seems to miss a line. I know the angle is too sharp, but the mesh can be generated normally before modifying the model.

You can create curves yourself in ICEM. Use the surfaces as a start:
Geometry -> Create/Modify Curve -> Extract Curves from Surface.
There select one of the surfaces and the missing curve will be created.


If you want to have more control over the mesh in your sharp angle, then follow this thread:

Mesh Is Not Following Trailing Edge Curve Correctly

Thank you, Gert-Jan.

Curve exist. What is missing is the line of Mesh. I tried to remove this curve, and recreate it. but the mesh doesn't seem to know this curve.

Define a thin cut. That usually works.
Press F1 for help with examples.
