We found situations of pedestrians being stuck. The reason is not found in the router. It works fine. To make the routing situation better readable and better for the programm (Distance among hlines increased.), we deleted some hlines in the stair-case. We attached our new Routing File.

The reason for pedestrians being stuck was very large wall forces. Below you find sample values:
repPed: ...( -0.22 / -0.77)
repWall: ..( 1.06 / 3.96)
e0: ......... ( -0.68 / 0.00)
direction:( -0.16 / 3.2 )
In a case, where the pedestrian should walk to the left ( -1 / 0 )

Solution: We changed parameter repWall: a: from 5 to 1 


<force_wall a="1" D="0.02"/>```

We are running a test with all groups enabled. If it succeeds, we close this issue and make a comment in our wiki.

I remember it to have worked. Current dev-branch (49873bc1) does not work.

It works with: global_router exit_strat 3

floorfield router will not work with this HH_geo.xml, because there are rooms with walls and doors, that share the same projection onto the x-y plane.
