solidificationMeltingSource: A Built-in fvOption in OpenFOAM® for Simulating Isothermal Solidification
In this chapter, I introduce, document, and verify solidificationMeltingSource: a built-in fvOption in OpenFOAM® for simulating isothermal solidification. The main challenge in simulating isothermal solidification is the incorporation of movements of the solidification front. To overcome this challenge, solidificationMeltingSource adds source terms to the momentum and energy equations. First, I rigorously derive the equations for these source terms and outline their implementation in the source code. Then, I verify solidificationMeltingSource by simulating a well-known numerical benchmark for isothermal solidification. Finally, I end the chapter by suggesting possible future extensions for solidificationMeltingSource.
