Example
Consider the pipe model from the previous examples. The global mesh size is set to a relative value of 0.1 and mesh size on the inflow surface is set to 0.0025. The mesh is generated by launching the mesh generator.

Figure 4. Cut Plane Clearly Shows the Boundary Layer Elements
As shown above, the default boundary layer settings are used. You can choose to use different boundary layer element types as well as choose different Resolve options.
