1. Installation Requirements
--------------------------------------------------------------------

- Administrator rights are required during the installation process.
- NVIDIA graphics card, with support for OpenGL versions higher
than v3.0.


--------------------------------------------------------------------
2. Supported OS
--------------------------------------------------------------------

- Windows Server 2012 R2
- Windows 7 64 bit
- Windows 8 64 bit
- Windows 8.1 64 bit

Sim4Life V4.2 uses Acceleware's Rotorua library version 11.1.12.
Please get the latest NVIDIA driver for your hardware
from the Acceleware website: http://acceleware.com/fdtd-11.1.12.

Please note that only NVIDIA GPUs with CUDA Compute Capability 1.3
or higher are supported by the S4L CUDA solver (e.g., Tesla C10XX).
The AXE solver supports only CUDA Compute Capability >= 2.0.

3. New Features & Enhancements
--------------------------------------------------------------------

3.1. Simulation

- EM-LF quasi-static solver can now use B-field data as input. 
This works by first reconstructing a vector potential field A from 
the magnetic field B. It allows using the EM-LF quasi-static solver 
with source fields computed using third-party solvers.


3.2. Analysis

- Coordinate transformation between measurement and simulation 
coordinate systems for far-field data
- New algorithm implementing Gamma dose comparison method
- SAPD algorithm can compute surface-average of power density 
using  either norm or normal component of Poynting
- On flat surfaces, surface-averaged power density can now be 
computed much faster using the new fSAPD algorithm 
- Export of stream lines from the streamline viewer
- User-defined analysis pipelines allow saving postprocessing 
workflows, so that they can be easily re-used
- Pipelines made of several postprocessing algorithms can be 
grouped into a single algorithm


3.3. Optimizer

- Optimization of coupled simulations
- Multiple optimization studies within the same project


3.4. Modules

- IMAnalytics v2: new features in Python Notebook, including 
normalization to B1 in slice and advanced plotting features


3.5. Python

- Several improvements on the Sim4Life Python API.


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