I wonder if someone has the experience to do the simulations for plastic or maybe metalic tanks like expansion tanks that have two seperated parts which have been welded together. I have been doing like this: importing two parts and then make them booleaned and then contact I make them tied. So this way the two parts are practically unical. But I do not know if there is another way to do this kind of simulation that the welding condition can also be considered like in the reality.
