*>>What changed values are you talking about in Static Structural?*

*What does the point mass represent?*

I wrote earlier that I changed the design of the valves, removed all unnecessary (bolts, nuts, etc.). Now, when calculating, I specify their mass separately using the Point Mass tool. So that the calculation takes into account the correct weight of the valves. Earlier, we discussed that there is pressure in the pipes and you advised me to set the pressure through the Static Structural module, then transfer everything to modal analysis, after which everything will go to harmonic analysis. My question is this. Is the Point Mass set only at the first stage in Static Structural (weight of pipes with water and exact weight of gate valves)? It's enough?
