Using IWAVE

William. W. Symes [*]

Abstract:

IWAVE is a framework for time-domain regular grid finite difference and finite element methods. The current IWAVE package includes source code for component libraries and commands, and examples of typical IWAVE acoustic modeling use cases. The examples are taken from a recent paper on error propagation for heterogeneous medium simulation using finite differences, and allow the user to replicate illustrations of the interface error effect which renders all FD methods effectively first-order accurate. This paper gives a brief tour of the common IWAVE use cases illustrated in the package examples.
