ALN is on a distinguished road

I do not understand why cfMesh creates such a mesh (see mesh.jpg file). Why vertical lines are not straight from top to bottom ? How to fix it ?

In meshDict, I have :

surfaceFile "bathywithbox.stl";
keepCellsIntersectionBoundary 1; 
keepCellsIntersectionPatches 1; 
checkForGluedMesh 1;
maxCellSize 500;


       cellSize 50;
       type box ;
       centre (720000 7590000 0);
       lengthX 100000;
       lengthY 100000;
       lengthZ 500;


Thanks !
