A Wide Range of Applications, covering Modeling, Analysis and Visualization

  • ■Many element groups specializing in engineering and construction are supported by material nonlinear models.
  • ■Exclusive elements for civil engineering and architectural fields, including a variety of material nonlinear models.
  • ■High-quality pre-posts integrated with TDAP III are applicable to wave processing and visualization. Available as an independent general-purpose tool.
  • ■Widespread use among customers, including research institutes, universities, construction companies, design offices and consultants.
  • ■High reliability with proven achievements High-speed processing

For 2-dimensional bridge structure models (degree of freedom:400), 5000 steps of nonlinear dynamic analysis can be processed within less than 7 seconds, using 1.8 GHz Pentium4 processor. For 3-dimensional models (degree of freedom: 2600, ArkFemView Sample), 5000 steps of quake-free nonlinear dynamic analysis can be processed within about 5 minutes.
