In this section the various solver properties will be specified in order to obtain the proper solution for the laminar pipe flat plate boundary layer flow. First, the axisymmetric nature of the geometry must be specified. Under General > Solver > 2D Space select Axisymmetric as shown in the image below.

Next, the Viscous Model parameters will be specified. In order to open the Viscous Model Options Models > Viscous - Laminar > Edit.... By default, the Viscous Model options are set to laminar, so no changes are needed. Click Cancel to exit the menu.
Now, the Energy Model parameters will be specified. In order to open the Energy Model Options Models > Energy-Off > Edit.... For incompressible flow, the energy equation is decoupled from the continuity and momentum equations. We need to solve the energy equation only if we are interested in determining the temperature distribution. We will not deal with temperature in this example. So leave the Energy Equation set to off and click Cancel to exit the menu.
