LoadDef v1.2.1

Minor bug fixes.

Contact: hilary.martens@umontana.edu

LoadDef v1.2.0

• Includes a new ability to use a common mesh for all stations when convolving load Green's functions with a surface load. This improves computational efficiency over using station-centered grids, especially for large networks.
• Merges special new features from separate branches into the main branch (e.g., option to compute Love numbers at depth, option to compute displacements from a disk load analytically based on the Farrell [1972] disk-factor formulation, option to remove the effects of gravity).
• Minor bug fixes.

LoadDef v1.1.7

The latest stable release of the main branch with minor bug fixes (LoadDef-main).

Additional branches designed for specific applications are also included:

• A function to compute load Love numbers at different depths inside a planet.
• A workflow to compute analytical Green's functions for disk loads using the Farrell (1972) disk factor.
• A version of LoadDef that will compute Love numbers and Green's functions without gravity (i.e., the equations of motion for spheroidal oscillation and surface boundary conditions have been adapted to remove the effects of self gravitation).
• A version of LoadDef with significant changes to the convolution workflow, including the option to use a common geographic mesh (rather than a station-centered mesh) and a re-formatting of the MPI to pass stations to processors rather than load files.

This release also includes a discussion board for users to share comments and ideas.

LoadDef v1.1.6

Includes new Jupyter notebooks for the primary programs.

Also includes a new tutorial with specific examples and visuals.

Warning -- for the latest version of LoadDef, always access from the main LoadDef page (e.g., git clone). The releases are only updated periodically and may not reflect recent updates and bug fixes.

LoadDef v1.1.5

The most up-to-date version of the software package can be accessed by cloning the current repository:
git clone https://github.com/hrmartens/LoadDef.git

Or by downloading a zip file from the main webpage for the software (green "Code" button at the top).

Warning: The release stashed here may not reflect recent changes and bug fixes.

The new release reflects updates to the linear interpolation algorithm used in the computation of the Love numbers -- the updated algorithm significantly improves computational efficiency. Thank you to Martin van Driel at ETH Zurich for discovering and implementing the opportunity to improve efficiency. Additional minor bug fixes and minor updates are also included in the new release.

LoadDef v1.1.4a

Minor bug fixes and updates added to v1.1.4.

This release reflects the software package before updates are made to the linear-interpolation algorithm (f_solid_linear.py) in the computation of the Love numbers.

LoadDef v1.1.4

29 October 2020

Minor bug fixes, such as maintaining consistent data types.

LoadDef v1.1.3

15 November 2019

The new release includes minor updates and bug fixes, including:

• Updated the string encoding for consistency in Python 3.
• Updated utility plotting functions to output PDFs rather than post-script files.
• Added the TPXO9-Atlas model to OTL scripts in the /GRDGEN/load_files/ folder.
• Removed the "factorial2" import in "fundamental_solutions_homsph.py" since it is no longer needed and may cause problems on some systems. Thank you to Chenfeng Li for bringing this to our attention.
• Updated the Anaconda installation instructions in the User Manual and quick_start.txt guides in the /doc/ folder.

LoadDef Software v1.1.2

The updated release contains a minor bug fix. For some operating systems, a TypeError was encountered when generating starting solutions from power-series expansions during the computation of Love numbers. Thank you to Gaohong Yin for bringing this to our attention.
