Abstract
A computer-implemented method for adaptive mesh refinement includes generating a first mesh for a first layer of a stacked model representing a 3D integrated circuit, the first mesh including a first grid for the first layer, performing a simulation for the stacked model using the first mesh to obtain first results, calculating an interpolated value for a particular grid node according to the first results, the particular grid node corresponding to a node of the first grid in the grid hierarchy. The method further includes generating a second mesh for the layer of the stacked model, the second mesh including a second grid for the first layer, performing a simulation for the stacked model using the second mesh to obtain a simulated value of the particular grid node, comparing the interpolated and simulated value, and generating a refined mesh for the first layer including a refined grid.
