Hello
I think you have simplified your model a little too much to have a representative simulation.
The thinks that the remote mass load is way too low to reflect reality unless your room is wall-mounted and the main load is down.
In addition, confirm to me that you did not only take the edges to fix the ground from a distance. The resistance overshoots on the sheet of your dodecadone seem to indicate this. It would be better to create wider areas with interior dividing lines to the volume.
I don't see the sense of gravity, which is mandatory for remote charges.
Anyway, let's get back to our sheep and the onions that keep them.
I assume that you are only interested in anchor bolts.
The first thing to do is to make a much finer mesh
Check that you have prestressed the bolts
If your part is welded on the soleplate then put before the simulation of the radii outside which will represent the welds. This will remove all or part of the tension in the corners and the deformations of the sole because we can see that the rear bolts seem unstressed, which is curious.
Look at your simulation in section to do so in results, click on result and select "design dissection" and there you will see the most stressed areas in depth.
You can use the slider to modulate to see the most or less loaded areas.
Because often you have surface tensions that do not exceed one mm in depth.
The deeper it is red, the more it sucks. ;-)
One rule: don't panic too much if you see red and never show the boss raw results with red.
Do not forget also in the results of the requested the safety factor because for your application it is the most important if you do not want to receive the hut on the dog's head.
Once these operations are done we will see for the rest ;-)
Kind regards.
PS: I hope I don't shake you too much with my remarks ;-)
I don't know you! ;-)
But know that I am benevolent, even if I avoid letting things pass by by not responding to the bare minimum of the request. We're between PROs after all.
