If you are seeking an online training course for OpenFOAM, I invite you to join my YouTube channel. I have uploaded a series of step-by-step videos that demonstrate how to conduct numerical simulations using OpenFOAM.
The own OpenFOAM post-processing tools are : postProcess and foamCalc. However, funkyDoCalc is a hell of tools. It makes life easier. If you missed run-time processing by an accident, and you don’t like to redo the simulations you may still can derive some results from saved data in time directories.
Some times when you are going to install a package from third-parties on linux, you may see several errors about missing files or libraries. The best approach is to install apt-file then search the library name through the repository.
OpenFOAM has two solvers (chtMultiRegionFoam and chtMultiRegionSimpleFoam ) for the simulation of heat transfer across different materials. When a solver has the keyword simple in its name in OpenFOAM, it means it uses SIMPLE algorithm for pressure-velocity decoupling, Moreover, it represents it is a steady solver.
The major two phase flow regime in the micro tubes is the Slug flow regime. In this case there is one or few bubbles inside the channel. Hence, it is usually using surface tracking techniques for simulation of two-phase flow in micro tubes.
Vortex shedding is a common phenomenon when a fluid flow passes around a body. Here, the vortex shedding of viscoelastic fluid around the oscillating cylinder is simulated. For simulation, a dynamic mesh library is added to OpenFOAM solver viscoelasticFluidFlow. The solver is available only in foam-extended versions.
