NICE DCV through the Web Browser for Linux and Windows
Previously there were different ways of connecting to instances for Linux and Windows. For Linux it was mainly VNC or SSH. For Windows you had the choice of Remote Desktop or NICE DCV.
In order to take advantage of GPU graphics instances for products such as Discovery Live or ANSYS AIM, the best option was NICE DCV.
However NICE DCV required non standard ports to be opened, and also required the installation of software on your local machine. It also required licences. This gave problems for many IT and finance departments.
Amazon have acquired NICE DCV so now they are providing an updated version of NICE DCV that works directly from the browser over the standard https port (443). And it’s completely free on EC2 instances!
CADFEM have packaged this up nicely for you so that you can use a unified connection mechanism to both Windows and Linux instances. Remote Desktop, SSH and VNC will still be supported for now, but we are considering discontinuing it in the future.
The CADFEM Self Service Portal now supports Enhanced Networking. Enhanced Networking is necessary to launch the new C5 and M5 instance types.
Enhanced networking uses single root I/O virtualization (SR-IOV) to provide high-performance networking capabilities on supported instance types. SR-IOV is a method of device virtualization that provides higher I/O performance and lower CPU utilization when compared to traditional virtualized network interfaces. Enhanced networking provides higher bandwidth, higher packet per second (PPS) performance, and consistently lower inter-instance latencies. There is no additional charge for using enhanced networking.
The Elastic Network Adapter (ENA) supports network speeds of up to 25 Gbps for supported instance types. This compares with the various Infiniband speeds as shown in the table below:
|25 Gbps||54 Gbps||40 Gbps||32 Gbps||16 Gbps||8 Gbps|
C5, F1, G3, H1, I3, m4.16xlarge, M5, P2, P3, R4, and X1 instances use the Elastic Network Adapter for enhanced networking.
Amazon have said that ENA will support up to 60 Gbps by the end of the year!
New C5 and M5 Instance Types
Amazon have released a new generation of C5 and M5 instances, with superior speed and network connectivity to the old C4 and M4 instance types.
We have worked hard to implement these on the Self Service Portal and they are now ready for prime time.

|Model||Real CPU Cores||Memory (GiB)||Linux Price (Ireland)|
And also remember these instance types support networking speeds of up to 25 Gbps!
Standardised Password Generation
We have made the Get Password function now work in the same way for Linux and Windows. This allows you to click “Get Password” regardless which OS image you are launching.

In 2017 Motor Design Ltd (MDL) and CADFEM have announced their close partnership.
The two companies share a passion for Simulation Driven Product Development and a commitment to the notion that Simulation is More than Software. The combination of software [Motor-CAD and ANSYS] and expert services provided by MDL and CADFEM allow our customers to develop better machines in less time.
MDL is a world leader in developing advanced software and tools for designing electrical machines. Our software, Motor-CAD, is recognised worldwide as class-leading motor design software. We use our expert knowledge of designing electric motors to provide software support to electric machine designers at some of the most prestigious aerospace, automotive and industrial companies worldwide.
CADFEM is one of the largest European suppliers of Computer Aided Engineering (CAE) and is the ANSYS Channel Partner in several countries including the UK, Ireland, Germany, Austria, Switzerland, India. We are experts in simulation across all physics – mechanics, fluids, electromagnetics, systems… We sell and support the full ANSYS portfolio and help our customers to exploit the full benefits of simulation in their product development.
Motor-CAD can be used to quickly and easily perform electromagnetic and thermal performance tests on electric motor designs. ANSYS can be used to bring calculations of electromagnetic performance and cooling to the next level of accuracy and to predict and minimise noise and vibration.
We look forward to presenting to you how the two powerful tools can be integrated seamlessly within the ANSYS Workbench Environment.
MDL and CADFEM:
Motor-CAD, key capabilities:
- EMAG: a fast 2D finite element module for accurate electromagnetic and electrical performance predictions
- THERMAL: Combines a lumped circuit and finite element thermal calculation for optimising the cooling system of a machine.
- LAB:Provides efficiency mapping and duty cycle / drive cycle transient outputs within minutes
ANSYS, key capabilities for motor design & development:
- Vibration and Noise prediction using ANSYS Mechanical
- Evaluation of Improved Cooling Concepts with ANSYS CFD
- Detailed magnetic loss and performance calculations with ANSYS Maxwell
Integration of Motor-CAD and ANSYS
- Motor Design Geometry
- Integration with ANSYS Mechanical, CFD, Maxwell
