--------------------------------------------------------------------
--------------------------------------------------------------------

Release Date:
19.05.2020


Sim4Life light V5.2.2 is a student edition of Sim4Life V5.2.2, 
a specially tailored solution for students to to gain insight into 
the world of computational modeling and simulation. The software is 
time-limited but free of charge and can be used to simulate various 
applications applying different physics solvers.  

This document summarizes the features and specifications of this 
release.

4. List of Main Bugs Fixed Since V5.2.1 Release
--------------------------------------------------------------------

- Case 129074: Significant accuracy improvement in Vector Potential 
reconstruction, in particular for coarse grid resolutions
- Case 128551: Fix a bug which was creating a duplicate of thermal
sources in a project when selecting 'Coherent' Sources option
- Case 125192: Fix of a bug which was causing the model of a 
different new project to disappear when clipping the previous model 
in a slice field viewer and saving the project 
- Case 125090: Fix a bug in EM LF Clone As function which was 
producing additional overall field sensor and Air material setting 
- Case 124666: Fix in Python API to display correct version number 
when running s4l_v1.api.application.run_application() 
- Case 117592: Fix of incorrect default values of electrophysiological 
fiber parameters
