OpenFOAM R libraries are a great contribution to CFD community and a powerful way tocreate solvers and other tools. Nevertheless in this creative process a deep knowledge of classes structure,both for value storage in geometric fields and for matrices resulting from equation systems is needed,becoming a big challenge for beginners.To help in this process a new tool attachable at gdb (GNU Debugger) is presented. It allows to analyzeclass structures in debugging time. This application is implemented by gdb macros, these macros canaccess to code classes and its data transparently, giving so, the requested information. Tool is tested indifferent application cases, such as assembling and storage of matrices in a scalar advective-diffusiveproblem, non orthogonal correction methods in purely diffusive tests and multiphase solvers based onVolume of Fluid Method. In this tests several type of data are inspected, like internal and boundary vectorand scalar values from solution fields, fluxes in cell faces, boundary patches and boundary conditions.As an additional feature data damping to file is presented.All these capabilities give to gdbOF a wide range of use not only in academic tests but also in realproblems.
