- +==== Example ==== 
 +An example using the ''AdvectionReaction'' solver to solve the age equation can be found in ''[ELMER_TRUNK]/elmerice/examples/Test_Dating''. For a steady 1D flow, the dating equation simplifies to dA/dx = 1/u and solutions are of the form A = ln(Kv) with u = v/v'.\\ 
 +Two tests can be also found in ''[ELMER_TRUNK]/elmerice/Tests/Dating'' and ''[ELMER_TRUNK]/elmerice/Tests/Density''.
