I have just attempted my first FEM attempt. here is link to the file.

The parameters for my experiment are as follows:
The plate is 16 mm thick and I used calculix steel as the material
A force of 10 kN will be exerted by a bolt in opposite directions, away from the centre of the plate in the first set of two bolt holes
A force of 5 kN will be exerted by a bolt in opposite directions, away from the centre of the plate in the remaining two bolt holes
A force of 5 kn will be exerted by another set of 4 snug fitting plates, away from the centre of the plate, in four directions on the face at the end of each of the slots.
I used a maximum mesh size of 5 and minimum of 3.
I am trying to establish whether or not the plate will be pulled apart under these loads. I am not an engineer but my guess is the week point is the two corners at the end of each slot.
On first a appearances it looks like I have a good result but I would appreciate an opinion from any of you nice
engineers on this board.
