RocPro3DThe professional tool for

3 dimensional trajectometrysimulations of rock falls

* Version 5.7, compatibleWindows 7, 8 et 10(32 and 64 bits)

Creating the mesh pointsBy import of point files (DXF, TXT, CSV, DEM format),level curve files (DXF format). The mapping of imagesis possibleBy level curves digitization of a scanned map, asRocPro3Dhandlesirregular triangular meshesBy input of a 2D profile of points (X, Z), to which awidth (Y) is then added

Building the meshBy Delaunay triangulation, or by grid triangulation forDTM with regularly spaced pointsBy import of any triangular mesh (PLY, 3DS, STLformat)

Mapping of soils onto the DTMEasy mapping of the soils onto the DTM thanks tomulti-modes selection of faces: selection by individualfaces, by zones, by ranges (altitude, dip, etc.)

Physical parameters ofsoilsIn an intuitive dialog box, each soil parameter (energyrestitution coefficients, rolling/sliding coefficient, limitvelocities and angles for transition phases, andassociated uncertainties) can be easily modified. Tomake use even easier,RocPro3Dprovides 6predefined soil types

Physical modelChoice of a rigid block (integration of the block massand rotation in the computation) or a lumped-massformulation

Rolling/sliding kinematicsFrictional rolling (rigid block) or frictional sliding(lumped-mass) model, integrated numerically ontothe DTM using a stable and accurate algorithm

Impact physical modelEffects of block rotation (rigid block)Standard (constant) or velocity dependent Rn

Choice of the computation modeDeterministic modeProbabilistic mode, with choice of equiprobable orGaussian variables

RocPro3Dallows to create a new project by extractionof an area from a existing project, while preserving thepositioning and the soil parameters

Block sourcesCreation of linear or surface sourcesNo limit on the number of sourcesSpecification of block settings (number,density,shape, size, starting conditions, associateduncertainties)

Choice of the computation strategyClassical computation, with display oftrajectories, easily achievable up to 20,000 blocksMassive computation, without limit on thenumber of computed blocks(1 million, evenmore), allowing an analysis with maps ofparameters and with protections statistics

For increased performances, computations canbe run in parallel on all your computer cores (thecomputation time is approximately divided bythe number of processors)

RocPro3D provides four main interactive andflexible views, allowing to analyze the results :

The 2D and 3D views, with data at each impactpoint (XYZ coordinates, soil, angles and velocitybefore and after rebound)

The vertical profile view along the blocktrajectories and the protection works,providingthe energy and height of the blocks

The graphs and histograms view for statisticalanalysis
