Introduction to Numerical Modeling in Geotechnical Engineering with Emphasis on FLAC Modeling

January 21-23, 2021  •  Zoom Online Meeting  •  Instructor: Dr. Siavash Zamiran, P.E.

MEA, Inc. of St. Louis, MO is hosting a 3-day workshop on Numerical Modeling in Geotechnical Engineering. The workshop will be on January 21 to 23, 2020  and will be taught by Dr. Siavash Zamiran, P.E.

This course is an introduction to modeling geotechnical problems using commercially available geotechnical programs with an emphasis on FLAC. Different geotechnical programs and numerical methods will be discussed and compared with each other. Principals of numerical modeling will be described. The modeling procedure for several practical geotechnical examples (including seismic loading) will be demonstrated using FLAC. The material is useful for students and professionals in different fields including civil, geotechnical, mining, petroleum, and geology engineering. Attendees will be awarded up to 8 PDH Credits for full registration.

Topics covered in the workshop include:

  • Introduction to Computational Geotechnics
  • Commercial Geotechnical Programs
  • Theoretical Considerations
  • Numerical Modeling in FLAC

“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.”

“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 Dr. Zamiran, 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.”
