Rock surface model, detect crossing with certain lithology
Hi I have created a rock surface model using "New mesh from offset points". The offset points are gathered from borehole data, at the soil-rock interface. As it is only the boreholes that are drilled in rock that is included, some of the boreholes which is only drilled in soil is passing trough the rock surface model. Is…

Structural beams and bars in non-linear analysis of QUAKE/W
I need to study the dynamic non-linear response of reinforced soil wall with anchors. Hence, I used structural beams for reinforcement and structural bars for anchors. However, there was error in the model which displays "Structural beams and bars cannot be specified with a non-linear analysis in QUAKE/W" What can be done…

LeapfrogEdge
Certainly! Successfully completing the LeapfrogEdge fundamentals training session is a substantial achievement for me. Despite the different outcome between training and final results, this difference often highlights the multifaceted nature of applying theoretical knowledge in practical settings. Engaging in training of…

Why am I seeing positive head above the water table in my seepage Model (SEEP/W)?
Hi All, I have a seepage model in SEEP/W where I am modeling a seepage flow due to storm surchage for a coastal flood wall. I'm looking at steady-state analyses (as an upper bound/worst case scenario with prolonged max flood water elevation) as well as transient analyses (with water surface rising/falling with storm and…

Two Identical Slope/W Models Returning Different Factors of Safety
I have two approximately identical slope/w models of an existing earthen embankment dam with different factors of safety. Both models consider a failure of the upstream slope of the embankment. The only difference between the two models is how the approximately same phreatic surface is input. "Model 1" has a phreatic…

MapInfo batch export XML format - cannot parse
Hi there, I am not a MapInfo user, but I would like to create an XML for batch import of spatial data. I have an XML that was not created by MapInfo, but rather by a standalone python code. When I try to import the XML (via , "GIS Data, Map and Photos" —> "Batch Import" —> From MapInfo" I get an error that Leapfrog Geo was…

Contact Surface Values
I am building deposit surfaces in a GM and i am getting bad results (segments of drill holes not included in the surface). When I display the contact surface values, some of the drill holes do not have any points at all or have incomplete points and that is why they are not being honored by the surface (or so I think). Can…

How do i get LF to interpolate better between borehole points
Good Day, i have attached an image of an issue i am having with LF. I am trying to create a geological model from borehole data. I have known points however LF does not interpolate between some of these points. See blue arrow in image. I have tried adding in manual manipulations using polylines shown with the block box on…

How to make contour map of coal seams floor SF, roof SR if a coal seam is model using vain system?
I'm doing model of big coal deposit that has 2 main coal seams that are intercalated with a lot of clay lenses. So I did my model using Vein System. I need to make a map of total coal thickness and seam roof and floor. How Can I do that from a Vein System volume model?

Grid normalisation
I want to normalise the existing values in grid to 0-1 i use the equation in grid math: G0 = (G1 - min(G1)) / (max(G1) - min(G1)) I also tried this G0 = (G1 - min(G1, G1)) / (max(G1, G1) - min(G1, G1)) But both do not work. please advice how to write the equation in grid math.

Calculate length, area and volume of each stretch in a tunnel
Dear all, I want to know how to calculate the length, area and volume of each stretch in a combined tunnel model. In other words, how to separate each stretch by the lithology used within the model, and show (either through a table or a report) its length, area and volume. Many thanks!!

GX Development unexpected error
I just started learning GX development with python. I installed the latest version 2023.2 of Geosoft Viewer. Also, I installed Python 3.8.3 and Geosoft Python modules and verified the installation. Now I am trying to run hello_world_extension.py, the very first example from the tutorial and getting error: A GXpy instance…

using one metal grade low CoG results in invalid value of other metal when reporting MRE
In the mineralization domain, there are Au, and Cu. Here I use eq(Cu+Au) to act as cut-off grade (CoG) to do Mineral Resource Estimation. eqCuAu means Cu +equvalent to Cu from Au when using CoG=0%, there are invalid in Cu grade and contained Cu; when using CoG=0.2%, there are still some invalid in Cu grade and contained…

Convert AGD84 to GDA94 easting/northing
Does anyone know the easiest way to convert from the AGD84 to GDA94 coordinate system? I registered my maps and cross-sections in Leapfrog under the AGD84 system, then exported them and uploaded them into a GDA94 system, but they still don’t align correctly. Any advice on what might be causing the issue or how to resolve…

Direction of seismic loads and the need for seepage analysis prior to stability analysis
For the stability analysis of embankment dam, what should be the direction of horizontal and vertical seismic coefficient. 1.What is the meaning of a positive and negative coefficient for both vertical and horizontal case? 2. For eg. for the stability analysis of embankment dam for d/s slope what should be the sign for the…

Anchor Support: Red box in front of slip surface
When I run my stability analysis with an anchor, it is showing that the support from the bonded zone is in front of the critical failure surface (as shown by the red box). When I make the anchor longer, this support goes away, which seems to me the opposite of what should happen. What is going on?

Issues with Topo
Hey, there - I am very new to the software. I have a question that's related to topography. I have sucessfully been able to get topography to import as a proper surface. Other times, it comes in as a block. I'm not sure why this is happening. I have tried doing .grd, .tif, and .asc files. All files are to the same extent…

How can i change the number of decimal places on an entry in my legend on a section?
I'm creating a cross section with a block model of a mag survey (discrete colourmap). My values are all quite small (3 decimal places) but the legend on the section will only display whole numbers. I can't see where I can add decimal places. Thanks for any help!

How do I get the estimated block model grade on my planned drilling via. the drilling prognoses tool
Using the drilling prognoses tools the leapfrog3d help segment suggests that planned drill holes can be evaluated against a block model: Planning Drillholes (leapfrog3d.com) There are two columns shown there, Au and GM. I have planned drill holes and I need to create a table of the approximate lithology and grade (from our…
