To perform such simulations, we have developed iRheoFoam, an open-source package implemented in the OpenFOAM framework. It is based on the Boussinesq–Scriven constitutive law and the Navier–Stokes equations, includes various solvers for both time-dependent and steady problems, and allows easy incorporation of new interface models and solvers, making it a versatile and powerful tooleninfo:eu-repo/semantics/openAccess33 Ciencias TecnológicasartículoComputational rheologyInterfacial flowComplex interfacesOpenFOAM
