+ * The following parameters of a enhanced floorfield can be changed:  
+        - __delta_h__: discretization/stepsize of grid-points used by the floor field  
+        - __wall_avoid_distance__: below this wall-distance, the floor field will show a wall-repulsive character, directing agents away from the wall  
+        - __use_wall_avoidance__: {true, false} switch to turn on/off the enhancement of the floor field  
+You can use them in the __ini-file__ in the following form:  
+```<model_parameters>
+			<solver>euler</solver>
+			<stepsize>0.01</stepsize>
+			<exit_crossing_strategy>9</exit_crossing_strategy>
+			<delta_h>0.0625</delta_h>
+			<wall_avoid_distance>0.8</wall_avoid_distance>
+			<use_wall_avoidance>true</use_wall_avoidance>```

   * 6: This strategy does use a floor field rather than heading towards a point on a line segment.
