Start to plan for plugging modmesh back to solvcon

[yungyuc]

solvcon is the predecessor of this project modmesh, but the code base of the former is more than 10 years old and unmaintained. modmesh was created to renovate the code using modern C++ and Python wrapping tools.

As modmesh is picking up the developer base and building essential features, including a 1D solver and multi-dimensional meshes, we can start to plan for further modularize the modmesh code and plug the modules back to solvcon, and fortify its solver constructing promise.

Currently, modmesh has primitive implementation of the following sub-systems:

1. Buffer management with simple array and simple collector.
2. Profiler.
3. 1D CESE solver.
4. Multi-dimensional static mesh definition (with only minimal test).
5. Qt/Qt3D/PUI-based GUI.

We should continuously build the features and build the module boundaries. In the end, solvcon will become a house for all modules and serve as the environment for constructing problem solvers.

This topic will also be discussed in the May scisprint on the 18th. In addition to the topic, the sprint will cover the following tasks:

1. Prototype profile data analyzer (conversation Prototype profile data analyzer #328)
   1. Wrap the call profiler (pr Add Python wrap to CallProfiler #315)
   2. Serializer of the call profiler (pr Prototype JSON serializer for CallProfiler #323)
2. Prototype more NRBC for the 1D solver (issue Add more NRBC treatment in the 1D Euler solver #330)
3. Prototype XY plot (and widget) based on Qt (instead of matplotlib) (issue Enhancing the navigation widgets by home-grown code #314)
4. Plot3d reader (issue Add Plot3d mesh format loader #331)
