From the developer:
A powerful computer program should be founded on advanced theory and be verified by tests and practice. The DYNAN program follows these guidelines. DYNAN is based on the improved Novak's method where a non-reflective boundary is formed between the near field and the far field to account for the mass of soil in the boundary. The program yields the dynamic response of both shallow and deep foundations under harmonic, transient, and random loadings.
