Re: Gmax, PWP, and damping ratio functions for cohesionless soils
Hi @BenanZahawi1,
GeoStudio doesn't have any pre-defined material properties for different types of soil.
However, you can find QUAKE/W example files here: Seequent Learning Center Learner Resource List. You just need to log in with your Seequent ID and Search "Quake".
Re: Spatial filter on the fly for easier viewing
Hi Josh,
Thanks for the response. I'll try out some of your suggestions.
One option for future functionality is to have different selection tools that allow a user to select certain boreholes/intervals in the scene and perform an action with them (e.g., "set all values in column X to 10" or "remove from view" or "omit from model/interpolation"); tools would be similar to those in ArcPro, like Lasso [my personal favorite], Polygon, and Rectangle. Also, the ability to add or remove boreholes/intervals from the current selection with CTRL and SHIFT without ruining the rest of the selection would be neat.
Re: Edit Category Selections in Point Data
Hi Samuel,
Are you using the most current version of Leapfrog (2024.1)?
Do you have a backup of the project from before your colleague reloaded the drillhole data?
If so, you can open the backup, and then export your interval selection column by right clicking on the column and choosing Edits > Export.
In your current project, you can right click on the interval selection column, choose Edits > Import and Delete Existing. This should bring back your edits in your interval selection column and keep them dynamically editable.
If you are not using the latest version of Leapfrog, or if you do not have a backup of the project, things become slightly more complicated.
You will have to re-create your interval selection column.
Step 1:Create a new interval Selection Column, and base it off of the column you used for your original Interval Selection (do not use the original interval selection column itself.)
Step 2: In your Shape list, switch the column you are viewing to the original interval selection column.
Step 3: Click on the Edit Colours button and hide all of the intervals except for one of the ones you want to recreate. Do not close this window.
Step 4: Click on the Select All Visible intervals in the top tool bar
Step 5: Click on the Assign To button in the Interval Selection window, select Create New Lithology, and give it the same name that it had in the original interval selection column. Then hit the save in the top toolbar (this might be overkill to do every time, however will save you a headache if your computer crashes)
Step 6: Go back to the other Edit Colours window, turn off this interval and switch to the next one. Repeat steps 4 and 5 for all of your original interval selections.
Step 7: Click Save one final time and close the interval selection toolbar.
You can now delete the imported column as your new interval selection is not based off of that column. The new interval selection column is dynamic and can be edited freely.
Remember to save a copy of your project before making any big changes, such as updating the drillhole database. The best way to do this is through Seequent Central, as your backup is safely in the cloud and accessible to approved colleagues in the event that your computer suffers a catastrophic event. It's also a great way to track the progress of the project through time and collaborate with colleagues.
Re: AGS Res2Dinv - Add known boundaries
Great spot! It seems the legacy version is a bit more forgiving when it comes to file format inconsistencies compared to the current release.
Re: AGS Res2Dinv - Add known boundaries
I finally found the problem: the z-coordinates are negative and must be positive. Now it works.
Sorry for the post.

This is a hands-on course covering basic concepts to advanced interpretation using public domain geoscience data from the Basin and Range Province in Nevada. A GREAT course if you're
- Working with, or have worked with, Grav/Mag data and are keen to brush up on your skills
- Interested in learning the best practices in incorporating Potential Fields data with other subsurface data
- Curious how Grav/mag can affect your interpretations
We are so excited to have Dr. Michal develop this custom course! This is a unique opportunity to be taught by one of the best!
AGS Res2Dinv - Add known boundaries
Hi everyone,
I try to do 2D inversion with a known boudary with the 2025.1 version of Res2DInv. My datafile is attached. The software does not seem to take the layer into account. Below a comparison of two inversions, the constrained one (first screenshot top) and the unconstrained one (bottom). The Legacy version takes into account the layers during inversion (second screenshot).
Does anyone have experienced this problem? Do you know if it's possible to fix it in the 2025.1 version?
Regards,
Angélie.
Re: Slope/W Probability of failure
Hi @DavidJersenius,
The probability of failure is determined by counting the number of safety factors below 1.0 and then taking this number as a percentage of the total number of converged Monte Carlo trials. For example, if there are 1000 Monte Carlo trials with 980 converged safety factors and 98 of them are below 1.0, then the probability of failure is 10%. Your slip surfaces show P(Failure)=0 because none of converged trials returned a factor of safety below 1.0.
The reliability index describes the stability by the number of standard deviations separating the mean factor of safety from its defined failure value of 1.0. That means Slip # 4851 is almost 20 standard deviations from failure. For context, 6 standard deviations would be a P(Failure) of 1 in 1 billion. So you could calculate P(Failure) from the reliability index, but it would be exceedingly small in your case.
Re: Implicitly Selecting a Mesh Partition After Clipping
We're modeling something similar to an S-C fabric. All shears are subvertical, but there are two orientations roughly less than 30 degrees apart. Major shears persist over longer distances, while the minor shears must terminate against the major shears.
Thanks for the great suggestion, I'll play with fault objects. That may be the solution I'm after.
Slope/W Probability of failure
When i do a probabalistic calculation i am among other things interested in the likelihood of failure for the specific Slope. That would be P(failure).
When i do the calculation i only get P(failure) for the most critical slope, why is that? Should P(failure) not be presented for all valid slope calculations?
