Hello everyone , just wanna ask a simple question.
The simulation is performed under structual mechanics.
Geometry is a cone, whose top redius is 0.009um, bottom radius is 5um, height is 9um. Material is silicon.
I applied a boundary load of 1e-6N total force (z direction only) on the top of the cone, and a fixed constraint on the bottom.
I run a stationery study. What I expected is that when I do the surface integration of von mises stress, the calculated force should be more or less 1e-6N, but what I get is 5.8e-9N.
Could anyone tell me what the problem is, please? Thanks a lot.
