Hi,
I hope you are doing well,
I am a new user of Comsol.
At this moment, I am trying to model a cantilever beam with an applied force on its edge as a function of displacement.
So, what I need is either:
define the force on the boundary as a function of displacement. I am trying to do this in equation view but it seems that it does not take expression and it asks me just values in x and y directions.
or:
write a PDE and try to solve it. The equation is derived from the Euler-Bernoulli theory as:
EI uxxxx=F(u)
I tried to find a predefined PDE and change the coefficients but I could not to do it.
Could you please help me on this issue?
