Frequently Asked Questions

Why is your software product called Met Dynamics Models? Is it for dynamic modelling only?

The Met Dynamics name was adopted for our consulting business in 2009 and represents our vision to address the causes and effects of variability in metallurgical and mineral processing operations. The name was extended to our software product on launch to align with our existing client base and industry awareness.

Whilst the Met Dynamics Models software product does include a range of dynamic simulation tools, the package is predominantly for steady-state simulation and analysis, in alignment with industry expectations and applications.

Met Dynamics Models is currently in version 2. What happened to version 1?

The development of Met Dynamics Models version 1 commenced in 2009 with the founding of the Met Dynamics consulting business. Models and tools were prototyped, debugged, improved and deployed to support consulting services. A limited number of clients were supplied with version 1 software, allowing them to simulate and optimise their own operations or support capital expansion projects.

A major revision of version 1 was was commenced in 2021, resulting in the version 2 software now offered as a commercially licensed product to the wider mineral processing community.

Are Met Dynamics Models in Excel compatible with the same models in SysCAD?

Yes. The same underlying Met Dynamics Models library code base is used by both interfaces. Model input parameters fitted in Excel, for example, will provide exactly the same model output results in SysCAD.

Are Met Dynamics Models compatible with the same models in other software packages?

All Met Dynamics Models unit models and tools are sourced from published material such as text books, scientific journal articles, and conference papers. Met Dynamics Models models and tools are therefore compatible with other implementations of the same models insofar as those implementations also follow the published source material.

For simple, well-documented or historically older models (e.g. Whiten crusher, Perfect Mixing ball mill) the input parameters are largely compatible between implementations, since compatibility is a consequence of following the model theory explicitly. Input parameter compatibility may be more limited for particular models that are less clearly articulated in the literature (e.g. AG/SAG mill) and individual results may vary.

Instances where Met Dynamics Models are known to deviate from the published literature are typically noted in the wiki page for the particular model.

Occasionally, gaps exist in published information and methods. In such cases Met Dynamics Models attempts to follow the spirit or intent of the original source as closely as possible, and differences with other implementations may unavoidably arise.

The Model theory section of each wiki page describes the exact implementation provided by the Met Dynamics Models product. Extensive references to original source documentation are provided throughout the wiki.

Is there a Demo or Evaluation version of Met Dynamics Models available?

A time-limited, fully-functional Trial version of Met Dynamics Models is available for evaluation. Please contact info@metdynamics.com.au to request a Trial version.

Are floating network, virtual machine, cloud infrastructure, or large volume licenses available?

Floating network, virtual machine, cloud infrastructure, or large volume license options for Met Dynamics Models are currently not available. Please check back again later as these options are planned for future releases.

What is the pricing structure for Met Dynamics Models?

Please contact info@metdynamics.com.au to obtain details of the Met Dynamics Models software pricing structure. Please provide information on your organisation's prospective use cases, target applications, number of users etc. to help us identify the best licensing options to meet your needs.

Are Academic licenses available?

We are able to provide generous discounts for the licensing of Met Dynamics Models in academic or other teaching environments. Please contact info@metdynamics.com.au for more information.

Can you please add model 'X' to Met Dynamics Models?

We are happy to work with both existing and prospective customers to build a model suite most suited to their their specific needs. Please get in touch at info@metdynamics.com.au to discuss requests for additional unit models. Met Dynamics maintains an extensive roadmap for future improvements and it is possible the desired model is already scheduled for development. Customer feedback, however, can assist in prioritising such improvements.

Can I include my own models and tools in Met Dynamics Models?

We can work with customers to integrate their own pre-existing models and tools into the Met Dynamics Models platform and interfaces. These models can be restricted to original customer use only, or released as a part of the full Met Dynamics Models package, according to the customer's desire.

What features, models and interfaces are planned for the future?

Met Dynamics maintains an extensive roadmap for the improvement of the Met Dynamics Models software product. This includes new steady-state and dynamic unit operation models, new mineral processing calculation tools, new software platform and API interfaces, as well as improvements and additions to the current suite of models and tools.

Please contact us at info@metdynamics.com.au for more information about future releases or to suggest particular improvements to meet your needs.
