Hi I'm in need of some help setting up a simulation of a load test of a grate (kind of a manhole cover).

The model name that needs to be tested is part named the 'heel guard'. This grate is simply supported along the 2 edges to simulate that it's sitting on a concrete surface (no clamping or sort).

A load of 210kN is applied on the grate via metal and timber assembly block.

To simulate the deflection of the grate resulting from the load, what type and where should the fixtures be defined to run the study?

I've also tried split lines to eliminate all other components as I'm only interested in the heel guard it self.

Thank you in advance.
