Question

e) Describe adaptive meshing.

FEA

Answer 1

Ans: neccessary if the same was done after adaption. Thus, adaption itself can happen in a more load balanced fashion. After adaption, the load balancing procedwe is invoked the load balancing procedure is invoked during the next interval, which then takes into account both computahonal and communication costs as described previously in calculating further necessity for load Q. Describe Adaptive mesting. Adaptive meshing can be carried out to define and/ or coarsen the mesh depending upon some user Specificed criteaja. Before adaphion, the cell which will be refined or coarsened are marked and repartitioning is carried out based on the post adaption cell distribution A simple balancing procedure is carried out based on the difference processors. Here the number of processors is fixed to be the cuocient set of procesor. If the computational Load imbalance is more than a specified through threshold and the redistribution time calculated is less than the Saving in enceunion bime, redistribution is (amied out before adaption actually takes place, the volume of cey movement is less than or equal to what would be balancing.

A dynamic adaptive meshing Strategy has been developed for the rapid thermal modeling of LPBF processes. this method keeps a fine mesh in the melt pool region which has the steepest thermal gradiends, while coarsening the rest of the mest updating the mesh each time steps as the heat source moves. → Dynamic and adaptive meshing are methods to concentrate the elements to regiony with large gradients. thus, increased computational efficiency can be obtained without sacrificing accuracy. Dynamic meshing denotes a technique where the user prescribed the refinement and coarsering of the finite element mesh.
