The non-uniform Local Fourier Basis (LFB) method is designed to optimize memory consumption and increase the performance of strongly heterogeneous simulations. A crucial part of this modification is spatial resampling at resolution interfaces. The performance and accuracy of the simulation are closely tied to the performance and accuracy of resampling. In practice, these two aspects are usually inversely related. There exist many approaches to interpolation with different sets of properties. The challenge is then to choose the appropriate method with an acceptable trade-off. In this poster, we compare several integration methods based on their performance in the resampling resolution interface and their impact on the accuracy of the entire simulation.
