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

SEMCAD X Matterhorn V17.4 uses Acceleware's Tauranga library version 11.1.13.
Please get the latest NVIDIA driver for your hardware
from the Acceleware website: https://acceleware.com/fdtd-11.1.13.

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


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

3.1. Simulation

- MQS Solver now relaxes the vector potential field (A-field) 
requirement as input and allows to only provide the magnetic B-field 
as excitation field.


3.2. Analysis

- New 5G Maximum Exposure Algorithm to find the largest power density 
that can be reached by a phased array antenna. 
- The new histogram/cumulative histogram filter enables the exact 
computation of isopercentiles and isovolumes.


3.3. HPC Computing

- NVIDIA Volta generation GPU architecture support, e.g., supporting 
GPUs like Titan V, Quadro GV100,  Tesla V100, etc.
- Update in Acceleware library to enable concurrent execution of jobs.


3.4. Python

- Several improvements on the SEMCAD X Matterhorn Python API.
