DIANA Finite Element Analysis - Dams & Dikes


A dam is a complex structure whose analysis requires the following element features:

  • wide range of analysis functionality - ranging from modelling construction phases to earthquake analysis and coupled phenomena
  • ability to model nonlinear material behaviour and time, or ambient, dependent material behaviour
  • opportunity to model interaction of the reservoir and of the foundation with the dam body
  • possibility to do all of this in an automated sequence, without the user needing to manually convert results from an analysis into input for the subsequent analysis

Why Use DIANA?

Finite element analysis of Dams and Dikes is a major specialism of DIANA FEA.   DIANA incorporates an extensive library of material models and analysis functionalities which are ideal for this purpose, eg.

  • phased (staged) construction,
  • soil-structure and fluid-structure interaction,
  • user supplied material models,
  • a large range of interface models,
  • a large displacement and large strain analyses,
  • material nonlinearity, time and ambient dependency effects,
  • and nonlinear dynamic analysis.

The program is structured to ensure that a range of different analyses can be performed in one analysis command sequence. 

In addition to the dam specific technical data and specifications below, see also the general functionality information (to the right of this page).  Our range of brochures are also available for download.  Or, if you have a specific question about DIANA that you would like to ask, please use the webform.
