Library for solving PDEse

In Parallel and Distributed Systems Laboratory we are working on a C++ library that is first and foremost focused on tools for solving Partial Differential Equations by meshless methods. The basic idea is to create generic codes for tools that are needed for solving not only PDEs but many other problems, e.g. Moving Least Squares approximation, kD-tree, domain generation engines, etc. Technical details about code, examples, and can be found on our documentation page http://www-e6.ijs.si/ParallelAndDistributedSystems/MeshlessMachine/technical_docs/html/ and the code https://gitlab.com/e62Lab/e62numcodes

This wiki site is meant for more relaxed discussions about general principles, possible and already implemented applications, preliminary analyses, etc.
