Ansys Lumerical products come with a GUI and a solve license. See Lumerical product components and licensing and list of licensed features by product for more information.
The engine/solver component allows running simulations on your machines. This article explains how many 'solve' licenses are required for various simulations, license types, and resource configurations. 'Solve' licenses are job and core/thread counted.
Enterprise solve and HPC licenses
One (1) solve license allows running a simulation job using up to 4 cores/threads. They are compatible with Ansys HPC licenses and can make use of Ansys Parametric Licensing. This allows for multiple jobs to share a single 'solve' license in combination with Ansys HPC licenses.
You can use the Ansys Parametric Licensing Calculator tool to determine how many licenses you require for your specific configuration.
Business (standard) solve licenses
A single solve license allows you to run a single job using up to 32 cores/threads. To run a job with more than 32 cores/threads an additional solve license is required for each increment of 32 cores used to run the simulation. The core/thread counting is unique for each job and cannot be shared.
Academic solve licenses
Behaves the same as the Business products. One (1) solve license allows you to run a simulation job using up to 32 cores/threads. To run a job with more than 32 cores/threads an additional solve license is required for each increment of 32 cores used to run the simulation. Academic products come with 4 solve licenses per product (1 GUI + 4 solve licenses).
License consumption examples
Default resource configuration
- Example: Running a single (1) simulation job on a local machine using 32 cores.
Ansys Enterprise: 1 solve license and 28 Ansys HPC Workgroup increments or 2 HPC Pack increments.
Ansys Business: 1 solve license.
Academic: 1 solve license.
Distributed resource configuration
- Example: Distributing a single (1) simulation on 4 machines with 32 cores (4 * 32 = 128 cores).
Ansys Enterprise: 1 solve license and 124 HPC Workgroup increments or 3 HPC Pack increments
Ansys Business: 4 solve licenses.
Academic: 4 solve licenses.
Concurrent parameter sweep configuration on a single machine
This is a good way to run sweeps when you have a powerful workstation capable of running multiple simulations at the same time.
- Example: Running a parameter sweep on one computer using 6 processes per simulation and 4 sweeps to run concurrently on a single machine with 24 cores.
- When the simulation runs, the job manager will show 4 sweeps running concurrently with 6 processes per sweep using a total of 24 cores.
Ansys Enterprise: 1 solve license and 40 Ansys HPC Workgroup increments or 5 Ansys HPC Pack increments.
Ansys Business: 4 solve license to run the job using 6 cores per sweep with a maximum of 32 cores.
Academic: 4 solve license to run the job using 6 cores per sweep with a maximum of 32 cores.
Concurrent parameter/optimization configuration across multiple machines
- Example: Optimization sweep is run on 4 computers on a local network using 12 processes each.
Ansys Enterprise: 1 solve license and 64 Ansys HPC Workgroup increments or 6 Ansys HPC Pack increments.
Ansys Business: 4 solve license run the jobs on 4 machines using 12 cores on each machine with a total of 48 cores.
Academic: 4 solve license run the jobs on 4 machines using 12 cores on each machine with a total of 48 cores.
