Description User Manual References Synopsis Fully range dependent wave theory model based on the expansion of the wave equation into normal modes. In a range dependent environment either the one way or the full two way coupling equations are solved for different boundary matching conditions. This is the benchmark solution for range dependent conditions which also gives the backward propagating field. Environmental Input Parameters Sound speed profile in the water and sediment at various ranges, but only one sediment density and attenuation.
Execution time is also proportional to the number of range increments.
The user has to specify a range increment for updating the environment and matching the fields at those ranges. A series of decreasing increment sizes should indicate when a stable solution is reached. The running time will increase linearly with number of range increments. FEPE does that for the parabolic wave equation. The bottom properties cannot be elastic.
