Volsung Help & Support

Volsung 2024.3

Volsung continues to lead the way in geothermal energy, offering cutting-edge modelling and simulation capabilities. From reservoir to surface network simulations, Volsung integrates advanced features such as microgravity and subsidence forecasts, tracer modelling, Monte Carlo analysis, and GPU parallel processing. These tools provide deeper insights into geothermal assets and empower users to make informed decisions for optimal system performance.
Volsung 2024.3 introduces significant enhancements to 3D data interaction and simulation performance:
  • Leapfrog interoperability: Interact with, edit, and manipulate Leapfrog volumes and surfaces in Volsung, including downsampling, terminating surfaces at elevations, and moving points in 3D.
  • Plotting feedzone data: Extract and plot data from sources and sinks for detailed analysis.
  • Improved phase algorithms: Experience faster run times with improved phase change algorithms.
  • Supercritical performance: Benefit from better time stepping and stability in supercritical models.
  • Flexible MINC boundaries: Set boundary conditions for specific MINC layers.
  • Particle tracking: Use the particle tracking method on a wider variety of grids, including those oriented at 45 degrees.

This release is driven by customer feedback, reflecting our commitment to addressing user needs and advancing the field of geothermal modelling.

Data types/formats

Open source library

Some of the libraries which Volsung is built on require us to make their source code available to users, for example under an LGPL license. Most users will never require these files. Use the links below to download the source code of the libraries:
Please contact us if you wish to alter libraries according to their respective license conditions and we will support you in your efforts.

Linux

Linux (Ubuntu and its Derivative Distros)

Note: If you’re new to Linux and want to try out Volsung’s exceptional NVIDIA GPU acceleration we recommend you try out the Linux Mint distribution with the Cinnamon window manager. You can test run Linux by installing the system on a second hard drive using dual boot or you can even run it on a large USB flash drive. The license files which we distribute will work under both Windows and Linux.

For the installation first ensure that your package repositories are up-to-date:

  • sudo apt update
  • sudo apt upgrade
  • sudo apt install libxcb-xinerama0 dbus-x11

If you plan to use GPU accelerated computing please correctly install your NVIDIA GPU first and ensure that the correct NVIDIA driver (version 460 or higher) is installed on your system. If you install a GPU later on you may need to reinstall Volsung.

Next run the downloaded installer binary from the command line:

  • chmod +x ./volsung-online-installer
  • sudo ./volsung-online-installer

Note if you do not have all required system packages installed then a terminal will pop up to install these missing packages.

SNAP Installation for Linux

For non-Ubuntu based Linux distributions you can install Volsung directly from the SNAP store. Please follow the instructions there.

Go to Snap Store

One small drawback of using Volsung as a SNAP installation is that it does not fully integrate into your desktop environment; i.e. you need to manually set the file associations so that double-clicking a file will open the corresponding Volsung application. How you do this depends on the desktop environment you are using; if you are using open desktop you can use the following scripts:

  • /snap/volsung/current/bin/install-icons
  • /snap/volsung/current/bin/install-mime-types

Note SNAP installations are maintenance free and will upgrade automatically when a newer version of Volsung becomes available.

Volsung python modules

We provide Python modules for interaction with Volsung model input/outputs. They can be used query model outputs of interest, for example to generate custom reports. Some modules also allow you to generate model input files (for example for Gudrun) using the Python API or to query the Volsung internal steam tables (Signy).
The modules are accessible from gitlab; please follow the download and installation instructions there.
