comment Mathematica not responding to clean start-up
@ilian I know that this has been answered elsewhere but can you post our chat transcript (which was a definitive solution) as an answer? I assume that is allowed (since this is the internet?)

comment Mathematica not responding to clean start-up
@Gansukh if you read the chat transcript between me and ilian (from a few comments above), you will find a solution described in there.

comment Mathematica not responding to clean start-up
I don't know what happened recently with mathematica and wolfram but I think my work has just been jeopardized by whatever it is (my fault or Wolfram's fault)

@ilian When I try to launch the frontend, it the spikey just stays at "initializing internal preferences".

@ilian Led me through a bunch of activation steps and then "The password you entered is not valid." Not fun at all.

comment Boundary value problem: complicated functionals
@SayaniMajumdar As late as this may be, out of curiosity, this looks like the Euler-Lagrange equation. May I ask what you are trying to minimize via this Euler-Lagrange equation? What physics are you trying to capture? A Lennard-Jones 6-12 potential?

comment Equal flow boundary conditions
Can you give us an idea as to what these two equations are trying to solve? Are they meant to be coupled somehow? The significance of the equation itself may allow for clues to help you.

comment FEM Solution desired for “Plate with orifice” deflection: Application of Boundary Conditions and use of Regions
If I were to modify this problem to have a point load, would I (just have to) use DirichletCondition`` for the load p0/De` at x=L && Y=h?

I would gladly share with you (and other mathematica developers) what I am using Mathematica+FEM for if you wish. I am a faculty in a technological university and one of my wishes is to have people use Mathematica for more than just as "scrap paper"

Thank you for confirming my deduction of XY plane.

I doubt that a 3D model would provide a different solution given the axisymmetric nature of the plate and the load applied. But this is definitely food for thought. It is interesting (and perhaps) to note that this FEM model in Mathematica surpasses in computation speed what is obtained through Hyperworks. Hyperworks doesn't allow the application of boundary conditions as derivatives and one is required to choose loose terms such as "free boundary" or "fixed boundary". My hope is to get mathematica significant recognition in my university's mechanical engineering dept.
