Changes since last release

Users: If you are working with the develop branch and your local code or project has been broken by a recent interface change then please see here for fix suggestions.

Developers: Please mention any changes to the code which will break users’ code here - to be put in the release notes for the next release. Also mention any significant improvements or new features. The real definitive release notes will be written in release notes at the time of release. To make that process easier, please structure this page in the same manner.

July 2023#

• #3089 #142 You can now have voids in bounded voronoi tesselations of cylindrical meshes.

April 2022#

• #3077 You can now add new and remove ghost nodes from mesh based tissue simulations.
• #3078 You can now bound the bound the Voronoi Tessellation’s on Cylindrical and Toroidal meshes.

September 2021#

• #3076 you can now output the underlying mesh during simulations with MeshBasedPopulationWithGhostNodes use SetWriteVtkAsPoints(true).
• #3043 added a Toroidal2dMesh which allows 2d mesh based simulations (with or without ghost nodes) with periodicity in x and y.

August 2021#

• #3071 Can now bound the voronoi tesselation in mesh based simulations by using the method SetBoundVoronoiTessellation(true) on the cell population. This works by creating a finite voronoi tesselation for each bounday cell, as described in Appendix A of https://doi.org/10.1007/s11538-023-01214-8. The extra nodes (used to bound the Voronoi Tesselation) are placed 1CD away from the tissue boundary to maintian an approximate voronoi cell diameter of 1CD.
• #3071 You can now output both the Voronoi tesselation (add VoronoiDataWriter) and mesh (SetWriteVtkAsPoints(true)) in mesh based simulations, the output files are now voronoi_results_xxx.vtu and mesh_results_xxx.vtu.

July 2021#

• #3069 You can now output the location (and other information Including the cell killer that removed it) of cell removals by immediate killing or apoptosis. To do this use the new CellRemovalLocationsWriter, this will give you the file removals.dat. To make sure the information is output you will need to update your cell killer (if not in the core code) to use the helper methods KillCell() and StartApoptosisOnCell() See TestCreatingAndUsingANewCellKillerTutorial for examples.
• #3069 and #2578 you can now output the division locations by using the CellDivisionLocationWriter (Formatting has been preserved see #3070)
