November 21, 2023, 12:23	Computing the new mesh in Lagrangian co-ordinates	#1
hunt_mat Senior Member Matthew Join Date: Mar 2022 Location: United Kingdom Posts: 175 Rep Power: 4	Suppose I am working in a 2D compressible elasticity. I am using Lagrangian co-ordinates , and I want to compute the new shape. How would I go about it? Naively I would solve the equations: $\frac{\partial x}{\partial t}=u$ $\frac{\partial y}{\partial t}=v$ I did that in 1D but I got errors, but I'm not sure about the parameters I used.
