Physical properties setup
- The physical properties of the fluid flow are located in directory constant
- Let us look in it:# ls $FOAM_RUN /cavity/constant
polyMesh transportProperties
- Inside this directory we can find a computational mesh and one configuration file transportProperties
- Usually, there are more configuration files presented, depending on the test case, solver and models used
- Let us print the file transportProperties content to the standard output:# cat $FOAM_RUN /cavity/constant/transportProperties
