Boundary conditions Memes

When your CFD simulation goes from solving partial differential equations to international politics in one boundary condition. Nothing says "I've given up on convergence" like adding a dictator to your flow field. The poor grad student who made this was probably on their 47th hour without sleep, surviving on cold coffee and mathematical despair. This is what happens when you tell engineers to "think outside the box" but the box is a domain with Dirichlet boundary conditions.
