These operators are then used to construct the equations to simulate-such as the Euler equations or the Navier–Stokes equations.īut in simulations where the material being simulated can move around (as in computational fluid dynamics) or where large deformations of the material can occur (as in simulations of plastic materials), the connectivity of the mesh can be difficult to maintain without introducing error into the simulation. In such a mesh, each point has a fixed number of predefined neighbors, and this connectivity between neighbors can be used to define mathematical operators like the derivative. Numerical methods such as the finite difference method, finite-volume method, and finite element method were originally defined on meshes of data points.
