There are many factors to check when it comes to Time problem-solving in Solidworks Simulation.
Can you please post the model so we can check what's wrong with your simulation study.
Please use the pack and go to gather all related files.
Firstly, not counting flanges, plates, etc., you have almost 70 different volumes that need to be meshed & run. You don't say what the details of your system are (including HD) but that would be the first place I look for a small assembly such as this.
Secondly, how fine a mesh are you trying to create? How many elements & nodes do you end up with?
Thirdly, how much detail are you trying to capture? Are you including fasteners? Do you have contact sets/bolt connections?
I agree w/ Mohammed, too many factors with just a picture.
Going to go out on a limb and suggest to convert all those uprights and crossmembers to shell definition if you are not using shells already. Possibly you could convert some to beams if you aren't interested in the behavior at joints.
