Mesh error in sheet metal part

Hi Guys,

I am new to simulations, and i think i am doing something wrong.

I am trying to check the deflection of an aluminium sheet.

After applying the fixtures and load I try to create a mesh but I keep getting a mesh error.

I have created a small surface at the center of gravity using the split line feature. I have applied a load on that surface.

I am attaching some pictures for reference.

I am using solidworks 2015.
