How to reproduce it (as minimally and precisely as possible): Dune and DuMuX master, compiling and running the test.
Anything else we need to know?: Maybe @melaniel can state the version & compiler details she used when generating the reference. I will be trying to reproduce a result tomorrow morning, too. Maybe it is compiler/machine dependent.
Environment:
- Dune version: master
- DuMux version: master
- Others: gcc 5.3 & gcc 7.4.4 (but with vel_1: 196.66% and vel_2: 135.84% difference)
