 # LDD simulation for two-phase flow systems (R–R, TP–TP, TP–R coupling)
 This project provides a Fenics based 2D domain decomposition code implementing an LDD solver for two-phase flow systems that 
-is part of the author's thesis.
+is part of the author's thesis [LDD schemes for two-phase flow systems](https://www.dr.hut-verlag.de/978-3-8439-4874-6.html).
 Two-phase flow systems means, that each subdomain can either adopt the full two-phase flow equations or the Richards/Richardson equation. 
 Flexible domain substructurings are possible so long as each subdomain has polygonal boundary.
