New Course: Dynamic Analysis of Soil and Rock Medium Using FLAC
Short Title: FLAC – Dynamic Analysis

In many geotechnical earthquake engineering problems, due to different variables from geometry complexities to earthquake ground motion characteristics and soil dynamic properties, conducting full dynamic analysis with the aid of computer simulation is inevitable. In this course, the procedure of fully dynamic analysis using FLAC and FLAC3D programs as powerful numerical modeling tools based on the finite difference method will be presented. Both 2D and 3D analysis procedures will be demonstrated. Several topics including model development, earthquake loading, dynamic boundary conditions, assignment of soil dynamic properties to the numerical models, and seismic response analysis will be discussed. Thorough discussions will be provided in liquefaction analysis of saturated soil layers. Other soil dynamic analysis topics such as blast modeling and dynamic analysis of vibratory foundations will be also covered.

What our participants say about FLAC courses…

“Anyone with solid background knowledge, looking for practical experience in continuum and discontinuum geomechanical modelling, will find the course a very robust and hands-on introduction to three of Itasca’s well-known numerical simulators. Working for a state mining regulator, I had so far relied on theoretical knowledge and common sense when it came to assessing study results obtained with the help of one of the programs. Thanks to Dr. Zamiran’s thorough lectures, the opportunity to ask questions and the chance to experiment with basic models of my own, I now have a much better understanding of the practical workflows, options and pit-falls in such undertakings. The course will be particularly useful to anyone planning to professionally use one of the programs in the near future.”

Geomechanics Engineer, Hanover, Germany

“I am a reservoir engineer dealing with the technical operational aspects of underground gas storage. It was really helpful to learn about the usage of the widely used numerical software packages in the industry and how they can handle praxis-oriented geomechanical problems on a theoretical basis. During the course, I learned how to investigate in the future my technical questions on my own with the help of technical descriptions of applied programs. Many thanks to our instructor and course trainer. With his help now I am ready to continue my technical education in the field of geomechanical modeling by the application of industry-leading numerical simulators.”

Senior reservoir engineer, Dusseldorf, Germany

“As a beginner in FLAC3D & UDEC, I found the course content and the examples explained very helpful. The course material and the recorded lectures were made accessible at all times during the course. Dr. Zamiran   was very kind to offer individual Zoom sessions to answer questions and help with the software. I strongly recommend the course if you are using FLAC, FLAC3D, or UDEC in your research or projects.”
