So i have a tank that needs a piping protection/support cage around it and i need to be able to see what the shell of the tank will do with the weight of the structure hanging from it. so i have it mated in place and weld beads all around but when i run the simulation and appy an extra downward force to the all the bottom beams, then ran the simulation. Now it will run for about 10 mins and then come up with an error message that reads this. "Check that you have applied adequate fixtures to stabilize the model." I need to know how to resolve this issue and continue to run the simulation.


all parts of the model will be attached.
