Hi, I am working on FEA of a assembly, during defining the force amount, i have some hesitation in concept.
Does the force per item mean that the applied force distribute on surface based on number of signs on surface or each signs have the force value that i have entered?
No. of arrows doesn't have anything to do with the item no. Item no is the number of different surface/entity selections you make. If you select two surface, e.g, and check per item, your force value will be applied to each of the selections. Goind through the tutorial would help.
That's exactly what i am thinking, I got different result in compared with theoretical method. I have to work more on my theory so. how about the gravity force, is that applied to center of mass of assembly or it is effect on results as a distributed force?
Gravity is applied to each node of the model.
Thanks.
