Abstract: The selection of mesh refinement and damping parameters, and the comparison of results to reasonable expectations, are challenging issues for the development of a numerical model in a dynamic analysis. Often it is possible to gain significant insight into these issues by conducting relatively simple analyses that are subordinate to those needed to address the primary purpose of the model. This case history presents a few such considerations for the seismic analysis of Clearwater Dam. The concerns addressed deal predominantly with frequency-related issues, but were conducted using software that performs analyses entirely in the time domain by an explicit solution scheme.
