I am attenpting to run a simulation under specific requirments i was given.
The simulation is a pressure vessel with legs welded onto it. That legs gets bolted to a containment frame, which then in turn gets bolted to a vessels floor.
I ran the simulation with the force of the liquid at a 30 degree static heel. I now have to add the following forces:
"Acceleration of +/-.5g parallel to the deckhouse" (simulating a vessel moving forward and backward)
"Acceleration of +/-1g perpendicular to deckhouse" (stimulating a vessel moving up and down)
My question is, is there a way to apply this force incrementally? Meaning the force starts at -1g and moves to +1g over a period of lets say 5 seconds.
My initial thought would be to multiply the mass (x1 for 1g and x.5 for .5g) and apply that force,but i need to show a time span of how these forces effect the pressure vessel moving. i cannot seem to figure out how to apply these force as described.
