Replies: 9 Computing the new mesh in Lagrangian co-ordinates Views: 271 Posted By hunt_mat Computing the new mesh in Lagrangian co-ordinates Suppose I am working in a 2D compressible elasticity. I am using Lagrangian co-ordinates (X,Y), and I want to compute the new shape. How would I go about it? Naively I would solve the equations:...
