FLAC - Dynamic Analysis

FLAC & FLAC3D for Earthquake & Dynamic Analyses

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.

What our participants say about Mohr Academy courses…

Markus H., Geomechanics Engineer, Germany

"Anyone with solid background and knowledge, looking for practical experience in geomechanical modelling, will find the courses and materials very robust and usefull."

Bela S., Reservoir Engineer, Germany

"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."

Ahmed A., Petroleum Engineering Ph.D. Student, USA

"As a beginner in FLAC3D I found the course content and the examples explained very helpful. The course materials and lectures were made accessible at all times during the course."

Kasgin K. B., Senior Geotechnical Engineer at Worley

"I took dynamic and earthquake modelling in FLAC course and enjoyed it very much. The videos presented by course's instructor, Dr. Zamiran, were very comprehensive and informative. The course was organized in a way to walk you through from fundamentals to practical examples. I recommend this course to anyone seeking intermediate level introduction to earthquake/dynamic modelling in FLAC."

Fedilberto G. A., Ph.D. Candidate at Queen's University

I have had the opportunity to assist several online courses offered by great companies and my experience had been satisfactory. On December 26th, I finished the course called "FLAC-Dynamic analysis" which is offered by Mohr Academy. I just want to mention that it has been my best experience with online courses so far. Difficult concepts were explained in a very simple way. Also, the variety of topics was beyond my expectation. This course had numerous hours of high-quality content. The quantity of online hours that this course offers is a great advantage.
