Geologic Model

Erosional (Soil) surface is extending and connecting boreholes which doesn’t have soil lithology.
So I have vertical boreholes (iron ore deposit) and top layer is soil. When creating erosional layer using the ‘erosion’ surface in Leapfrog Geo as can be seen in the Fig. 1, resulting erosional layer is extending and connecting the boreholes which don’t even have soil as layer (yellow bold dots are soil layer and…
Leapfrog Works: How to limit the extent of a deposit from offset surface, using polylines
Hi there I want to create a thin superificial deposit and thought that this is best done by a "New deposit" or "New erosion"… "From offset surface", using the topography. This gives me a surface layer which extends along the complete topography. But I want it to be present only in some areas and I have polylines which give…
Leapfrog generating "open" volumes for some units in the Geological model
Leapfrog calculates zero volumes for several units marked by an exclamation mark in the project tree and by "false" closed status in the properties. All these units display as expected in the 3D scene view. I.e. they are far from having zero volume in reality. Also, they are surrounded by units for which the volumes were…

Updated System Requirements
As the recommended system requirements haven't been updated since 2019, (when the recommended Graphics card and processor were released. Do anyone have any recommendations on the hardware for an optimal system? We are running some data heavy models which are taking days to process. I would like to build a dedicated system…
Balanced Shapes using the Intrusion Tool
What methods do folks find best to generate "balanced shapes" when using the Intrusion tool. An example being a narrow Intrusion shape (with an 65deg inclined structural trend applied) that has a limiting exterior point on one side from an adjacent drillhole, but unconstrained on the other side. Left to run freely the…
How can i edit blank spaces in a volume of a geological model?
I created a geological model from meshes that i created from a set of xyz points. Because they did not have the same distance between them, there are some blank spaces in the volume that was created like the one on the picture and in the limits of each unit: How can i fixed that?
Creating 3D models from a map - no other data
Hi, I am new to Leapfrog Geo. I am wanting to create a 3D model from a cross section and a plane view map. I have georeferenced these images but not sure how to define lithologies from the maps (I have created a legend) and create 3D volumes purely from the maps. Any suggestions on my possible workflow? Thanks :)
Surfaces rejecting borehole data
I have this organic material layer I'd like to model as an intrusion. Its in black. The boreholes are are oriented at about the same elevation, with 1 in the back and 4 in front here, with decreasing size of the organic layer. When I model as an intrusion, I get the front leftmost and back boreholes to connect, but the two…
Scene not displaying parts of surfaces
I'm working on the Oliver Training Project as part of Leapfrog Geo Fundamentals course. I've successfully created erosion and vein surfaces however the intrusion and deposit surfaces don't display on the scene, they get cut off part of the way through. Slicing isn't the problem. I've tried troubleshooting to the best of my…
Control on the type of displacement of fault
Hello all, I have 2 faults (non intersecting) in a single model. How I control the displacement of the veins, like 1 will be strike-slip another normal.
How to join two different geological models
I am using Deswik Mapping, and I want to export the contacts to create a small geological model; then, I want to join with the Main Geological Model to update it.
Feature Request: Rotate Boundary Boxes
I keep running into issues with geological and numerical modelling that would be easier to solve if I could rotate the axes of boundary boxes away from the N-S and E-W axes. This is especially problematic for drill fences which are not aligned N-S or E-W...something which happens quite frequently. Are there any plans to…
setting maximum thickness of a layer
Using Leapfrog Works: We are working in a setting with mostly unconsolidated deposits, some of which only occur as thin layers draped on the underlying topography. Is there a way to constrain the thickness of a certain layer or to set it to a maximum thickness, along the lines of "layer A must not exceed 5 m in thickness"?…
Export Roof & Floor from geological units for Modflow
Hi there! I'm trying to export roof and floor from each unit of my geological model, but these are highly dipping, and are also eroded by alluvium on top. So when I try to export the mesh parts of my younger and older surface I get the lateral contact and part of the topography. What would be the easiest way to export roof…
Layer guide option grayed out when creating Modflow model from GM
I'm trying to create a new modflow model from my geologic model with 6 layers but the "select layer guide" option appears grayed out. Why is that and how can I correct it so I can select all layers, not just the top and bottom of the model?
Fixing CSG error locations
I have had an issue when building a faulted geological model using borehole data. When I developed the initial unfaulted mode, there was no issue at all and it processed fine, however when I use the same data to create a faulted model, several fault blocks do not process correctly, with units sitting side by side instead…
How to change the coordinates of a model
Hi, a customer would like our exported IFC data of the geological models to be in a different location. Originally the coordination point was at x=0 and y=0. These should now be moved with an offset of x=3488500 and y=5474000. This is not a problem for the designs or borehole data, but is it possible to move the geological…
What's your best workflow for digitizing plan view geology from 2D section using drilling data?
I think the title is descriptive. I am trying to 1) Digitize section geology including lithology, faults, and alteration shells (not sure if I should use GeoStrings or figure out how to get PLY files to work). 2) Use my section geology (various dips) to quickly and effectively digitize plan-view geology. I have tried using…
Why my surfaces are not consistent with the volumes I create with them?
I am building a geological model from Drillhole data, the geothermal wells have its lithology defined but the volumes are not consistent with any surface. I don't know if I'm missing something or I'm doin it wrong. I'll thank any help.
Intrusion Variogram - Derive Variance
When modeling intrusions and employing the variography, there is a "variance" reported at the top - how is this variance calculated? The data to model my intrusion is categorical so where numbers are coming is a mystery. My only guess it is something to do with the interval lengths?
Transfer all of a GM user-defined constraints to a new GM using a different drillhole group
Best way to transfer all of an existing GM user-defined constraints, including resolutions, interior/exterior clipping boundaries, variance, sill range, drift, accuracy, etc.. to a new GM within the same project, which is using a different drillhole group and merged tables, using the same column headers. Hence, we need to…
Surface mesh extent extrapolate beyond model boundary.
Hello everyone. I am having some uncertainties about surface generation in LeapfrogWorks. In model boundary, I enclosed the object on the interval table and modified the model boundary extents for the purpose of my research. Even though I fixed up the model max and min boundary, Leapfrog is still extrapolating beyond these…
Is it possible to create a cubic slice?
Hi, I was wondering if there is a way to have 2 slices active at the same time, to cut a cube shape out of my ground model to show the geology in a specific area of the model. Thanks in advance
Custom topography extents
I have a Leapfrog Geothermal model with the standard XYZ extents that make a nice square, but am I able to customize the boundaries? My advisor wants it to look like this (picture attached) and suggested I "cut it to this shape" but I'm not sure how to make the boundaries diagonal. The picture is looking straight down and…
