Mesh independence analysis
WebMesh dependency occurs when a given fixed type of element and free mesh, is discretized using h-refinement method, in which the solution may depend on the size of the finite element. What is residual Ansys? A residual for the density-based solver is simply the time rate of change of the conserved variable ( ).

Web7 dec. 2024 · Mesh Independence Analysis In the reference case, the inlet temperature and the mass flow rate of the LBE are 473 K and 19.18 kg/s, respectively. Besides, the heated rod surface is specified with a uniform heat flux of 463,000 w/m 2. Firstly, the effect of the mesh refinement is analyzed qualitatively. Webmesh_size = [63984,142014,346431] parameter = [0.00324461,0.00306612,0.00304778] Which is plotted as. It is quite clear the the curve is leveling off, but isn't quite flat yet. How would I implement Richardson extrapolation to estimate a value of parameter at mesh_size = infinity? I would appreciate some help in how to implement this numerically.
WebSTUDY OF MESH INDEPENDENCE.
