_This tutorial illustrates the setup and solution of low mach number laminar jet flow.

This tutorial demonstrates how to do the following:

• Generate the mesh using the built-in mesh generation tool.

• Set numerical control parameters.

• Set gas properties, initial conditions and boundary conditions.

• Set physical models for a low Mach number laminar jet flow.

• Set output parameters.

• Generate and check the GASFLOW input file, ingf.

• Plot the calculation results.
