![]() ![]() Adaptive mesh refinement methods attempt to selectively refine the region of the mesh that is estimated to contain proportionally higher solution errors. In either case, convergence to the correct (measured) solution is not guaranteed. Similarly, depending on the geometric complexity of the object being modeled, uniform refinement can be inefficient since regions that do not need refinement add to the computational expense. Depending on the electrical size of the problem, uniform refinement of the mesh may be computationally infeasible due to memory limitations. Convergence of the simulation can be assessed by uniformly increasing the mesh density until an observable quantity stabilizes. Adaptive Mesh Refinement for Microelectronic Device Designįinite element and finite volume methods are used in a variety of design simulations when it is necessary to compute fields throughout regions that contain varying materials or geometry.
