In the Menu Bar of the interface one can find menu entries:

There is also an information panel showing the IGMAS+ version number (e.g. 1.4.8837), the name of the loaded project (model, e.g., salt.model) and its timeline version tag (e.g., V_2023-09-29_10_53).

The timeline version tag shows the date and time when the model was saved last time and is given in the format: V_YYYY_MM_DD_HH_mm, where

V stands for version
YYYY is the year
MM is the month
DD is the day
HH are hours
mm are minutes

The search panel can be used for quick access to the search functionality on this website:

A search request is constructed in the following format:

https://igmas.git-pages.gfz-potsdam.de/igmas-docs/?q=request

where request is what you search for.

File¶

File menu entry consists of the following sub-entries:

Project-related menu entries:
- New Project is used to create a new project
- Open Project is used to load an already existing project
- Save Project and Save as are used to save the current modified project.
- Close Project is used to close the current project.

Import / Export menu entries:
- Import is used to import data
- Export is used to export data

Exit is used to quit

The typical file load/save functionality is implemented in Open Project and Save Project menu entries. Both Save Project and Save as allow you to save the project within a folder. In both cases IGMAS+ will ask after a directory name and a new directory (global folder) and subdirectory (timeline folder) will be created. This directory structure keeps the valuable information about project changes over time. In this way the user can always recover old and current models.

Import and Export entrees can be used for data exchange with other software products.

It is possible to import the following data to IGMAS+:

Borehole
Model
Stations
Interfaces
PointSet (set of points)
Lines
Image
VoxelCube
Project (XML)

It is possible to export the following data from IGMAS+:

Body Parameter Table
Boreholes
Model
Stations
Interfaces
VoxelCube
Border-VoxelCube
StressMap

Exit¶

Menu entry Exit is used to quit IGMAS+. Before closing, IGMAS+ will check for changes in the project and a corresponding dialogue will pop up:

Edit¶

Edit menu entry consists of the following sub-entries:

Add sections
Model - Triangulation
Preferences
Options
Undo and Redo

Add sections¶

Add sections will open the sectioning wizard:

It is used to generate new vertical working sections, usually it is needed to get a higher flexibility for the structures.
The sections are constructed by cutting the complete triangulated domain with section planes, and build polygons out of the resulting cross sections.

Warning

To use the sectioning wizard you must be sure, that the triangulation is up-to-date.
In doubt, use Edit → Model - Triangulation or once.

The wizard shows the area where your model is located. Change the values according to your needs:

Define the distance (Spacing) between the newly created working sections
Change the number (Count) of them

Use Preview to update the preview of the working sections on the right.

It is also possible to adjust the area in which the working sections are defined:

To define the area, either move one of the white circle, or click one of them with right mouse button to use numeric input.

The green color shows the side which is used as a first section. In the figure above the southern side of the rectangular area is used is a first working section. In the figure below the western side of the rectangular area is used is a first working section.

Select Preview and then Finish once you are ready and run Edit → Model - Triangulation or again to update the triangulation.

If you want to reset the current configuration of the working sections, use Reset.

See also the Simple Basin example for a use case.

The same sectioning wizard is used when importing horizons, with the only change is that there you can also control the direction (azimuth) of the sections:

Tip

You can also change the orientation of newly created work sections if you have previously deleted all existing sections.

Model Triangulation¶

Model - Triangulation or will open the model triangulation wizard:

You decide if you want to recompute the anomaly at the same time after the triangulation.

The triangulation wizard checks the model vertices for potential triangulation error:

Example of a potential model triangulation error

In case of a potential triangulation error, the wizard shows the section where the problem has occurred, the corresponding body to which the affected polygon belongs, and the respective coordinates. In the simple example above the error has been caused by the intersection of a body with the boundary of the model:

Intersection of interfaces causing a potential model triangulation error

Even if there are potential error reports, you can run the triangulation by pressing Finish, and the final triangulation can still be successful. After triangulation of the model, the actual validity of the triangulation is automatically checked for:

Completeness: each body has to be surrounded by a complete hull of triangles
Orientation: the hull of triangles has to take the orientation of the triangles into account.

The result of the triangulation check is shown in the Status Bar:

In the example above both the Completeness and Orientation conditions are fulfilled, therefore triangulation is successful.
However, the resulting model doesn't make physical sense because it does not correspond to a realistic geological configuration and a potential field response calculated from such a model is not comparable to a measured data.

Warning

Even when triangulation is successful, the model can have no physical sense

In the contrast to the situation shown earlier, triangulation for a more complex model with the section shown below produces several errors:

Actual triangulation errors detected after validation

The reason for the error is that the Completeness criterion is not fulfilled. The problematic vertices in each section are highlighted with red.

JVM Settings¶

In Research → JVM Settings user can adjust the following settings related to the Java Virtual Machine (JVM):

Initial heap size: When JVM starts, its heap space is equal to the initial size of heap memory specified by this parameter. As application progress, more objects get created and heap space is expanded to accommodate new objects. Usually it is not needed to adjust this value.
Maximum heap size: The JVM expands heap memory in Java somewhere near to maximum heap size specified by this parameter and if there is no more memory left for creating new objects in java heap, JVM throws java.lang.OutOfMemoryError and application dies. Adjust it if you have problems with loading or creating a big model.
JRE for IGMAS+: Version of the JRE used by IGMAS+.
Proxy settings: Setup proxy settings for internet connection, if needed.
Stereo Settings: User can force stereo rendering which can help to overcome potential visualization issues.

Tip

See more information on how to adjust the JVM settings here.

The JVM settings window can also be accessed directly from the system without starting IGMAS+.

In Windows just start typing IGMAS+ settings in the Start Menu to find the shortcut:

Note

You should restart IGMAS+ for changes in the JVM settings to take effect.
