Convergance study

Hi guys I am having a problem trying to get my simulation results to work.  The table below shows the results I am getting. The displacement goes from 57 to 0.8 just by changing the global mesh size by 1?!

 

Global mesh size in SOLIDWORKS2122
Elements55122153
Displacement8.83E-015.72E+01

 

Yet in previous tests;

 

2224.527
323725002153
5.72E+014.50E+021.93E+02

 

There is a bit of a pattern, however oddly enough when the mesh becomes fine, the results go up and not down

 

Mesh Density14.51719.5
Elements978278976135
Displacement1.37E+001.24E+001.09E+00

 

Does anyone know what is going on?

For the record I have done a similar simulation in Abaqus with a different model - my results were as follows.
