I modeled a nozzle with displacement in the vertical direction (Y). Our client does not let us model the equipment.
As the loads are a bit higher than the admissible ones, I try getting them by introducing the nozzle flexibility.
I had a mysterious problem with the output.
Cases are:
1 (HYD) WW+HP
2 (OPE) W+D1+T1+P1
3 (SUS) W+P1
4 (EXP) L4=L2-L3
Then, on the connection
Load Case FX FY FZ MX MY MZ
2(OPE) -317 0 133 -44 -165 -215
3(SUS) -17 -1301 -77 464 -9 -141
4(EXP) -300 0 210 -508 -156 -74
L4 is not L2-L3 in the vertical direction, where I indicated the displacement.
I cannot understand where the trouble is.
Please, help me.
