This tutorial illustrates the setup and solution of hydrogen diffusion into air in a 1D duct. This tutorial demonstrates how to do the following:
Generate the mesh using the built-in mesh generation tool.
Set numerical control parameters.
Enable the second-order discretization scheme.
Set gas properties, initial conditions and boundary conditions.
Set physical models for a species diffusion problem.
Set output parameters.
Generate and check the GASFLOW input file.
Set the remote GASFLOW server and run a calculation.
Plot the calculation results.
1) GASFLOW input file
2) Comparison to the analytical solutions
