 ANSYS CFX
 =========
 
-[ANSYS CFX](http://www.ansys.com/Products/Simulation+Technology/Fluid+Dynamics/Fluid+Dynamics+Products/ANSYS+CFX) software is a high-performance, general purpose fluid dynamics program that has been applied to solve wide-ranging fluid flow problems for over 20 years. At the heart of ANSYS CFX is its advanced solver technology, the key to achieving reliable and accurate solutions quickly and robustly. The modern, highly parallelized solver is the foundation for an abundant choice of physical models to capture virtually any type of phenomena related to fluid flow. The solver and its many physical models are wrapped in a modern, intuitive, and flexible GUI and user environment, with extensive capabilities for customization and automation using session files, scripting and a powerful expression language.

 ANSYS Fluent
 ============
 
-[ANSYS Fluent](http://www.ansys.com/Products/Simulation+Technology/Fluid+Dynamics/Fluid+Dynamics+Products/ANSYS+Fluent)
+[ANSYS Fluent](http://www.ansys.com/products/fluids/ansys-fluent)
 software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants. Special models that give the software the ability to model in-cylinder combustion, aeroacoustics, turbomachinery, and multiphase systems have served to broaden its reach.

 ANSYS LS-DYNA
 =============
 
-**[ANSYSLS-DYNA](http://www.ansys.com/Products/Simulation+Technology/Structural+Mechanics/Explicit+Dynamics/ANSYS+LS-DYNA)** software provides convenient and easy-to-use access to the technology-rich, time-tested explicit solver without the need to contend with the complex input requirements of this sophisticated program. Introduced in 1996, ANSYS LS-DYNA capabilities have helped customers in numerous industries to resolve highly intricate design issues. ANSYS Mechanical users have been able take advantage of complex explicit solutions for a long time utilizing the traditional ANSYS Parametric Design Language (APDL) environment. These explicit capabilities are available to ANSYS Workbench users as well. The Workbench platform is a powerful, comprehensive, easy-to-use environment for engineering simulation. CAD import from all sources, geometry cleanup, automatic meshing, solution, parametric optimization, result visualization and comprehensive report generation are all available within a single fully interactive modern  graphical user environment.

 ANSYS MAPDL
 ===========
 
-**[ANSYS Multiphysics](http://www.ansys.com/Products/Simulation+Technology/Structural+Mechanics/ANSYS+Multiphysics)**
+**[ANSYS Multiphysics](http://www.ansys.com/products/multiphysics)**
 software offers a comprehensive product solution for both multiphysics and single-physics analysis. The product includes structural, thermal, fluid and both high- and low-frequency electromagnetic analysis. The product also contains solutions for both direct and sequentially coupled physics problems including direct coupled-field elements and the ANSYS multi-field solver.
 
 To run ANSYS MAPDL in batch mode you can utilize/modify the default mapdl.pbs script and execute it via the qsub command.

-To get a certificate, you must make a request to your local, IGTF approved, Certificate Authority (CA). Usually you then must visit, in person, your nearest Registration Authority (RA) to verify your affiliation and identity (photo identification is required). Usually, you will then be emailed details on how to retrieve your certificate, although procedures can vary between CAs. If you are in Europe, you can locate your trusted CA via <http://www.eugridpma.org/members/worldmap>.
