Hi! I am doing a basic normal analysis for a tank and I am trying to add full water inside, I have tried already to add a mass on the gravity point to simulate the tank with water inside but the result does not change much( I have asked to a teacher during training and he said I have to add a structral mass but I do not know how to do it) while at the same time I found out that in Hypermesh it is possible to set Mfluid card to simulate the situation with the impact of liquid even without creating mesh, how fantastic! But the problem is that the tank's shape is complex so I can't use hex mesh, instead with tetra mesh there is not positive and negative direction of the mesh, no? On the other hand, I am more familiar with Simlab so I wonder if this function is also available in Simlab? If the answer is no, either I need to find a solution still in Hypermesh(midsurface or midmesh but I am not sure about the result's accuracy because for another model the results between Simlab and Hypermesh are with 15Hz difference).
I would be very grateful if someone could give me some suggestion, I am feeling that this case is not that complicated, maybe there is a very simple way that I don't know about… thank you all!
