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.

Once the mesh is imported into AcuConsole the surface mesh size on the inflow is found to be finer than the surface mesh on the outflow. Here the mesh generator used the smaller of 0.0025 and 0.005m for the inflow surface, and 0.005m everywhere else.

Now, consider adding boundary layers to the wall surface. The boundary layer attributes are set in the Surface Mesh Attributes panel. Mesh attributes are de-activated on the inflow surface. Once the mesh is generated with these settings, boundary layer elements are generated.

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.
