The current attention in improving the efficiency of mining energy minerals from the earth has encouraged concern in advances, difficulties and likely forthcoming development directions in numerical modeling for rock mechanics and rock engineering. Such modeling is necessary for studying the essential methods occurring in rock, for considering the anticipated and actual performance of structures built on and in rock masses, and hence for supporting rock engineering design.
You must start from the available manuals. It is very extensive and complete.
and then retrace the examples that are shown. In the youtube channel Itascacghttps://www.youtube.com/user/itascacg/featured
you can find many useful things.

You can also start by reading related papers which detail the basic steps undertaken in FLAC3D modelling. There are some good papers available on Itasca website. Moreover to get hands on experience you can also download the demo version from Itasca website and try with given example codes.
Hope this helps.
Hi Niaz,
I would suggest starting with the manuals available in the packages. Those are the best references and explain the software very well and step by step. I especially recommend "Getting Started" and "Command Reference".
Mr. Niaz, first thing you should keep in mind before starting to learn either FLAC3D or 3DEC that it not practically possible to learn the entire software at one go. Therefore, the beginning of learning of software should be problem specific. For example, if you have to design a pillar, knowledge of brick mesh generation would be sufficient, and you should control one’s temptation to learn not waste you time on other types. Furthermore, if you have griddle or Kubrix available with you, you should learn designing of shape using Rhino, meshing using Kubrix or Griddle and not invest your time on manual meshing; thereby, you can skip ‘Grid Generation’ section given in manual.
You may start with getting started section of the manual. Examples are given to make you comfortable with interface; you copy and paste the examples in text (or data) file to run the commands interactively through file driven mode. Command and plot windows can be opened simultaneously and text files can be called to develop an understanding of each keyword. If you want to see the how a keyword functions, you can insert comma before other lines to make them read as comments. Even after this if you are confident with any keyword, you may search it in command reference which describes every keyword in detail. After developing confidence with software interface, you may read ‘Problem Solving with FLAC3D or 3DEC’ section to develop an understanding on selection of material, meshing, stress initialization etc. After all these you will have a solid foundation to take up any problem for simulation. For project specific case, you may find a similar example in ‘Example Applications’ or ‘Verification Problems’ section.
After following above steps, you will have sufficient understanding and confidence to play with the commands or keywords to get any desired outcome.
I hope you find above suggestions helpful. Best of luck with your project.
Very helpful suggestion. Thanks for your attention. Ajeet Yadav
Hi Wang
Thanks for your motivation. I'm trying by best. Guijun Wang
Ajeet Yadav Thanks a lot for your comprehensive answer.
I want to ask one question regarding modeling of fracture inititation, propagation and geometry using Flac3D.
I am new in this regard. Can you suggest me easiest and most effective workflow for this problem because I donot want to waste my time on things which are not needed at this time.
Thanks a lot for your time.

Mehtab Alam From 12 Meeting, 2 Meeting is learning FLAC 3D. Include 1.Tunnel Mechanized Excavation and 2.Earth Dam
The best way to learn FLAC3D is to follow the instructions given in the user manual. If anyone want detailed description of how to create grid in FLAC3D please let me know, i had a PDF which describe the step by step instruction to create 3D grid.

This is a pdf which describes the step by step procedure of creating a grid using extrusion in FLAC3D.
Dear Niaz Muhammad Shahani,
Below are some publications made using FLAC3D software :

You can find the manual after installation of the FLAC 3D software...
Sreenath Sekhar sir, Can you share the FLac documentation pdf to [email protected]
Thank you.
Dear Niaz,
The Itasca's programs generally operate in similar stages. You can use Phase2, Geo5, even Plaxis (if you need to process by numerical methods). if you are faced with complex environments, DDA, FEM-DEM, 3DDGM are recommended.
Before using any program, I must say that it is the geotechnical characteristics of the site are dictated to using the software. Software selection before site inspection is not professional. You have to go to the site, conduct the field survey, gather data; then regarding the geo-engineering status of the site select a relevant software/program.
