Hi Amer,
The modeling is ok ... though I have some doubt over the fixed but support conditions along the two peripheries. Please have a relook for the "FIXED BUT FX MX MY MZ" and "FIXED BUT FY MX MY MZ" conditions. Otherwise the model has no instability, statics check is satisfied and displacements are realistic too.
You have mentioned that the support reactions are too much. I suggest you to review the load values, whether they are as per your calculation.
