Visualization

At the end (or after the first write), execute paraFoam -case Fluid & to visualize the channel and add the Solid.foam file from the ParaView menu. Please note that the extension .foam triggeres the internal reader of ParaView and should work in most versions. You may use the reader provided by OpenFOAM if you change the extension to .FOAM.

If you want to convert the results to VTK, you may use the command foamToVTK, optionally with the -ascii flag.

As soon as you load both cases in ParaView, you may use the filter Group Datasets to apply your settings in both domains at the same time.

An example of the visualized expected results can be found in overview.png:

Observe that the temperature at the bottom of the plate is 310K and at the inlet 300K. On the interface, the temperature is between these values. An area of higher temperature is formed above the plate, which is shifted towards the front, driven by the flow.

You may use additional filters, such as the Calculator and the Plot Over Line, to obtain the distribution of the non-dimensional temperature (T-T_inlet)/(T_solid-T_inlet):
