@Peter and @Rich, thank you all for your comments.
I will try out the examples tomorrow and think about Peters observation.

Re: FlowSolver: wrong results in 1-dim pipe flow problem
Thank you for replay and for the information about the convention in Elmer, that positive normals shows into the solid. Today, i checked the calculated normal vectors in Elmer (Module: NavierStokes.F90, Subroutine NavierStokesBoundary) and they where calculated correctly. Therefore, the problem is n...

Re: FlowSolver: wrong results in 1-dim pipe flow problem
Hi Community again, An Addendum: Maybe the problem is due to inconsistency of normal vectors of the surfaces of my mesh. I made the mesh with GMSH and exported it to Elmer via ElmerGrid: gmsh -3 -format msh22 flow.geo ElmerGrid 14 2 flow.msh -removelowdim -bulkorder -autoclean Thanks, Carsten Broese

FlowSolver: wrong results in 1-dim pipe flow problem
Dear ElmerTeam, I want to model a 1-dimensional pipe flow with FlowSolver and get wrong results for the output velocity. Model Options for FlowSolver are: Stokes flow, incompressible, vanishing viscosity, no body forces. The pipe is of rectangular cross section and modeled in length (x-direction) by...
