I am trying to use random fields to simulate the uncertainty of soil profiles (in 2D and 3D) in FLAC. I want to ask everyone, is there any example that can clearly explain how to do this simulation, either in FLAC or other software packages?
Hi Mahdi,
See this paper.

Dear Mahdi,
For the normal distribution, there is a command in FLAC. If your distribution is different you can use FISH to simulate.
I cannot say about FLAC, but Random Fields are implemented “out of the box” and “easy to use” in Optum G2 (normal and lognormal distributions with Karhunen-Loeve expansion as a generation method). They have examples.
In addition, there is a lot of information and examples on DIANA FEA, but I do not use it, unfortunately. So, I cannot tell you much. If I am not mistaken, many types of generation methods and various non-Gaussian distributions are implemented there. There are many theses and articles, also a webinar on using it in DIANA.
Jauheni Kazlouski answer is correct, we have possibilities for 2D and 3D random fields in various options and purposes.
best regards Ab
