The goal is to provide simple MATLAB style functions for the generation and manipulation of meshes, fields, and matrices. The library is based on the MEDCoupling C++\/Python library of the SALOME project for the manipulation of meshes and fields, and on the C++ library PETSc for the handling of matrices and linear solvers.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>SALOME provides the functionalities of SolverLab library via the module SOLVERLAB.<\/p>\n\n\n\n<p>The module includes PDE systems arising from the modeling of nuclear reactor cores which involves fluid dynamics, heat and neutron diffusion as well as solid elasticity. It is a simple environment intended for students and researchers to teach and promote new numerical methods on general geometries with unstructured meshes. The main research objectives of SOLVERLAB are the study of:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>numerical schemes for compressible flows at low Mach numbers on general meshes<\/li><li>well balanced schemes for stiff source terms (heat source, phase change, pressure drop)<\/li><li>numerical handling of flow inversion, phase disappearance and counter-currents in two phase flows<\/li><li>numerical handling of stiff porosity or cross section functions<\/li><li>schemes that preserve the phasic volume fraction \u03b1 \u2208 [0, 1]<\/li><li>convergence of finite volume methods<\/li><li>new preconditioners for implicit methods for two phase flows<\/li><li>the coupling of fluid models or multiphysics coupling (e.g. thermal hydraulics and neutronics or thermal hydraulics and solid thermics)<\/li><\/ul>\n\n\n\n<p>The library is currently maintained and distributed by the SALOME development team on various Linux distributions (Ubuntu, CentOS, Fedora, Debian).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SolverLab is a geometrical and numerical C++\/Python library designed for numerical analysts who work on the discretisation of partial differential equations on general geometries and meshes and would rather focus on high-level scripting.
