The webinar discusses running ANSYS simulations in the cloud on Microsoft Azure using UberCloud, highlighting how it provides 53% faster performance than on-premise clusters for a 100 million element ANSYS airfoil benchmark, allows scaling simulations from 32 to 512 cores, and offers benefits like lower total cost of ownership, global accessibility, and elastic licensing based on core-hour usage.

extruded to give 3D meshes of various sizes
o Turbulent SST, ideal gas, heat transfer
o Default advection scheme (high resolution)
• Global mesh size: 104,533,000 nodes 103,779,720 hexahedral
elements
Benchmark Details
• Suitable for 100s of partitions
• Number of iterations: 5
• Uses Large Problem Partioner
• Partitioning memory requirement: 28GB
• Partitioning time: 15min on Intel 5670
• Solver memory requirement (total): 140GB

6. BYOL Perpetual or Leased Licenses.
ANSYS Elastic
Licensing with ANSYS
Elastic Units (AEU)
Based on core-hour usage and
solver.
- ANSYS HPC Packs
- ANSYS Parametric Packs
ANSYS Licensing in the Cloud
Example Scenario
Large model, calculation time 13 days.
Elastic Licensing - Use AEU for FLUENT and HPC Packs
Prices include high performance hardware on Azure, UberCloud license &
service, and additional license cost for Fluent and HPC packs.
Reduce Cost by
Choosing Licensing That
Matches Your Needs

10. FASTER TIME TO MARKET
GLOBAL ACCESSIBILITY
UNLOCK NEW CAPABILITIES
There are huge benefits for engineers
CONFIDENCE IN YOUR ANALYSIS

11. Software
Maintenance
ANSYS upgrades !
(typically 4 times a year)!
Benchmarking
Benchmarking your model on
different Azure cluster sizes using
ANSYS benchmarking models!
Ongoing Operations
Adding/removing nodes from the cluster
(this is a big benefit and money saver
since the entire cluster is not needed 7x24
at peak capacity)!
Support
Break fix services when cluster
nodes fail!
Training
Training on how to use the services
(transfer files, monitor jobs, etc)!
Initial Setup
Setting up and validating ANSYS
software, MPI (parallel processing)
on the Azure cluster !
Also great benefits for IT
$ Lower TCO
