Fluent setup and solution using settings objects
------------------------------------------------
This example sets up and solves a three-dimensional turbulent fluid flow
and heat transfer problem in a mixing elbow, which is common in piping
systems in power plants and process industries. Predicting the flow field
and temperature field in the area of the mixing region is important to
designing the junction properly.
This example uses settings objects.
**Problem description**
A cold fluid at 20 deg C flows into the pipe through a large inlet. It then mixes
with a warmer fluid at 40 deg C that enters through a smaller inlet located at
the elbow. The pipe dimensions are in inches, and the fluid properties and
boundary conditions are given in SI units. Because the Reynolds number for the
flow at the larger inlet is ``50, 800``, a turbulent flow model is required.

Import mesh and perform mesh check
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Import the mesh and perform a mesh check, which lists the minimum and maximum
x, y, and z values from the mesh in the default SI units of meters. The mesh
check also reports a number of other mesh features that are checked. Any errors
in the mesh are reported. Ensure that the minimum volume is not negative because
Fluent cannot begin a calculation when this is the case.
