Slab edge meshing

I have a 6-sotrey RC building 10m x 20m. The slab edged are slightly offset from the walls and requires a very fine mesh to run (0.22m) without showing the 'kinematic constraints' error everybody seems to get. This causes the program to run very slow when performing a seismic analysis as I believe the load is shared between all the nodes at floor level.

 

Is there a way of easily adjusting the slab edge or auto-detecting they are together? Prefereably without revisiting the Revit model which was hard enough to align in the first place.

Please use plain text.

Try to define structural axes at the location of the walls and use the detailed correct option. You may also indicate the plane by 3 corners of a wall. The idea is to match slab edges with walls.
