Should I add gravity to this simulation?

I want to simulate if a sheet metal pedestal(with a 6.5kg stuff attach on top of it) can resist 17 Beaufort scale wind force

Should I turn the gravity on?

I saw most simulation tutorials usually don’t turn on this load.
I have tried adding gravity, the Safety Factor has improved a lot, but I don't know if this is accurate.

Hi, my guess is that you check your design on displacement.

safety factor is based on the von misses stress and could be in accurate because off irregulates in your part

Can you File>Export and then Attach your *.f3d file here?

One of my colleagues used the safety factor to make judgments, although we all know that this may be inaccurate.

I would idealize the model for analysis.

Is there a particular component that you are interested in?

I would assume you don't need the base.

I would assume that you don't need the hex fasteners (which are only the heads)?

I would assume that you don't need the end cap.

Perhaps you don't even need the "sign".

All of this has to be meshed and might not be of interest in the analysis.

I suspect that all you need to analyze is the column with perhaps the square flange and gussets.

I didn't dig any deeper to check the constraints and loads... (but I would expect Gravity to have an insignificant effect on this analysis on or off).
