Topic: Meshing and Loading

Dear All,

1) How I can refine my mesh to specific area, for instance, finer mesh closer to steel and coarser mesh beyond steel?

2) I am simulating four point bending test, applied same load on steel plates, but in L-D diagram both load have different behavior. In real case both load should be same, how I can enforce a condition that load always behave same.
Is it a right way, if I model a new steel plate above an existing two steel plates and apply a single load centrally ?

Regards
