In this talk I will provide motivation and rationale for developing freeCappuccino open-source library for computational fluid dynamics and in general computational continuum mechanics. The code is based on finite volume method on arbitrary unstructured polyhedral meshes. The interfaces to highly abstract data types such as arbitrary order tensor fields on discretized finite volume domains, and scalar and vector sparse linear systems resulting from finite volume discretization of partial differential equations are provided. Explicit manipulation of tensor fields through high level, highly abstract programming syntax is explained. Also, implicit operation over tensor fields pertinent to discretization of partial differential operators is provided and explained. The library is developed in modern version of Fortran. The purpose of the ongoing development is providing researchers with a tool for easy transfer of mathematical operations of their physical models into functional and efficient simulation software based on finite volume method. The guiding principle of development is exchange of ideas and reproducibility in computational science in general. The application for laminar, turbulent flows, heat transfer will be discussed, as well as some illustrations for non-newtonian flows, cardiovascular flows and magnetohydrodynamics (MHD). The potential for academic, research and industrial use as well as collaborative development will be discussed.
