How to create topography surface for FLAC 3D?

12 December 2022 1 8K Report

I want to modelling 3d dynamic analysis for earth dam in Flac 3D. I have read several article. Kubrix-Geo can help to make Topography surface, but i cant found the software yet. Even in itasca website. Is there anybody help me, how to create topography surface for Flac 3D in simply way?

FLAC 3D seems to accept DXF and STL file formats, and Kubrix-Geo seems to be part of the Itasca suite ( Ref: "Kubrix Geo - offered by Itasca and described as: a stand-alone product requiring an ASCII STL input file from any solid modeller" in Article New open-source ANSYS-SolidWorks-FLAC3D geometry conversion programs

). So there a great variety of 3D modeling software out there and all of them can import and export DXF and STL.

By 'Topography surface', do you mean a way to make a LIDAR point cloud or DTM/DSM/DEM into a mesh, which can then be imported? A 'simple way' depends of the data you are working with. I've used various CAD programs, GIS software, and utilities like Cloud Compare ( https://www.danielgm.net/cc/ ) and even Blender (https://www.youtube.com/watch?v=t9CH-cg8scc ). All of them have some learning curve.
