# ReactMiCP {#reactmicp_file} ReactMiCP is a reactive transport solver with the following features : - Sequential Iterative Algorithm [SIA] algorithm - Flexible, allow user-defined system, equations, models, extensible... - adaptive timestep - - Two systems are currently defined : - saturated system - unsaturated system The user can use or extend these systems, or define new ones. The next files presents the solver in depth : - @subpage reactmicp_governing_file - @subpage reactmicp_solver_file - [Adaptive timestep]() - [Saturated system]() - [Unsaturated system]() - [Defining a new system]()
