 # One-phase flow with with random permeability distribution (and a tracer model)
 
 ## Problem set-up
-This example combines a stationary One-phase flow in a porous medium with randomly generated permeabilities with a tracer model. In the first step, the groundwater-velocity is evaluated under stationary conditions. Based on the velocity field the tracer model is running instationary.
+A contaminant tracer is diluted by diffusion and a base groundwater flow from the bottom to the top. The permeability within the domain is randomly distributed.
 
-## Random permeability generation
+### main file
+This example combines a stationary One-phase flow problem with a tracer model. In the first step, the groundwater-velocity is evaluated under stationary conditions. Based on the volume fluxes, the tracer model is solved instationary. Therefore both, the problem_1p.hh and the problem_tracer.hh have to be included in the main file.

+In lines 83-192, the stationary 1p problem is setup and soved and the volume fluxes are calculated for the tracer problem.
+In lines 193-292, the tracer problem is set up on the same grid and solved instationary.
