MUSICX webinar questions and answers

What are the main benefits of MUSICX versus MUSIC 6.3.0?

MUSICX has been re-designed and re-written into modern software coding platform, maintaining all the capability of MUSIC V6.3 but gives users additional functionality and the benefits of modern software architecture.

In the present release, MUSICX allows you to combine your MUSIC models with eWater Source (and the new Source plugin - Urban Developer) to model both water quality and quantity.  A limitation is that MUSICX and Source will have to run at the same time step. We are working on providing a solution where the three models will be able to run at different times steps, appropriate to the scale of the different tools. This will ultimately give  you the tools to design truly integrated water resource management solutions.  

The new coding platform brings the ability to customize your MUSICX models by developing plugins. Plugins can be written for a wide range of purposes, including to incorporate or test new treatment options, add new contaminants, recognize local features, such as soil type and hydrology or to include new science. Compatibility with the Source platform also allows you to access Source plugins, such as additional Rainfall-Runoff models.

MUSICX also brings the benefits of:

·        Improved Graphic User Interface for easy data input, tabular input/output, group edit and advanced graphics.

·        Function Manager to support more complex model building.

·        Powerful in-built Results Manager for data analysis and results interpretation.

What new opportunities will MUSICX support?

A primary driver for developing MUSICX was to support the integration of MUSIC functionality with eWater Source (including the Urban Developer Plugin) to allow for a holistic assessment of water quality and quantity water, giving water modellers and managers the tools to design truly integrated water management solutions. 

MUSIC and Urban Developer were designed to complement each other and were able to draw together information on water quantity (Urban Developer) and water quality (MUSIC) to develop IWRM solutions in urban areas. These models can now be linked to Source catchment and river system models. Giving water managers tools to explore possible interactions and to identify and test IWRM options across catchment and local scales, with a range of land-uses.

Users can customise MUSICX by creating plugins. Plugins can currently be created to for data processing, input sets, exporting and reporting functions.

Does MUSICX have any new capability or science?

This question answers several questions around new functionality and incorporating new technology or science, such as the type of contaminants, sediment and nutrient models, rainfall-runff models, treatment methods and new science.

MUSICX has the same underlying science and capability as MUSIC 6.3, including types of contaminants, treatment nodes, source nodes, rainfall-runoff and infiltration models.

eWater is a not-for-profit, Government-owned company, tasked with the ongoing development and adoption of Australia’s hydrology modelling tools. All our revenue, from licences, support and maintenance agreements and project work are re-invested into maintaining and improving our tools.

Over time, we envision that together with the MUSIC user community we will add new science and capability through the creation of plugins. Similar to our approach for developing the Source platform, we will work with the MUSIC community to identify priority areas and opportunities to co-invest in projects that support the ongoing development of MUSICX. Potential areas for plugin development include:

·        new contaminants

·        customized pollutant generation algorithms

·        new treatment types, such as a separate treatment pit

·        reflect the seasonality of nutrient treatment

·        additional rainfall-runoff models

We recognize the importance of gaining widespread acceptance from the MUSIC community on how to best include new features. Plugins will allow the community to test new approaches and treatments, from which we can work together to determine the best approach for representing new science and capability in MUSICX.

How can unique or local conditions be incorporated?

MUSICX has been designed to allow users to incorporate plugins, as described above plugins allow you to incoporate local conditions, such as soil characteristics and hydrology.

How do I write a plugin?

eWater provides training in writing plugins. To ensure that new plugins meet the required standards, we require all those who want to write plugins to complete this training.

Licensing, pricing and support

This answers several questions related to licencing and pricing

We are currently offering all those with a a current MUSIC Support and Maintenance Agreement a MUSICX licence at no additional cost. Contact us via User Voice or [email protected] to find out more or to upgrade your SMA to take advantage of this limited offer.

New users can purchase MUSICX licences as a:

       perpetual licence fo a single user, locked to one computer – Standard licence

       floating (network) multi-user licence

       Plug-in (with Source) licence.

The standard perpetual licence has a one-off cost of $5000+GST and includes the first 12 months of basic support (IT and software support). Single use licences can be purchased online, contact us at [email protected] to discuss network and multiple user licences. NB: MUSICX is a stand alone product, it does not need to be run with Source.

Support and maintenance packages for MUSICX remain the same, including user documentation and the help function.

Compatibility between MUSICX and MUSIC 6.3 and transitioning to MUSICX

This answers several questions related to compatibility.

eWater established a Technical Panel of MUSIC experts to guide the development of MUSICX. In collaboration with the Technical Panel we undertook extensive testing to ensure that results from MUSIC 6.3 are reproducible in MUSICX, this included regression testing by eWater’s hydrologists and members of the Expert Panel set up to advise on the development of MUSICX.

MUSIC 6.3 files (.msf) can be imported to MUSICX. When you import MUSIC 6.3 to MUSICX you will need to configure climate data. MUSICX accepts a variety of data formats including; .mlb (MUSIC meteorological template file), .csv, .txt and .dat.

MUSIC 6.3 cannot import MUSICX files.  

MUSICX is a major change to the software. We know that some of our community need time to learn the new features and transition to MUSICX. To ease the transition, MUSIC 6.3 remains available for use and eWater will continue to provide support services.

Is MUSIC-link available?

MUSIC-link is an important feature of MUSIC, it brings Local Government, stormwater modellers and land developers together to streamline the process for assessing the compliance of Water Sensitive Urban Designs (WSUD). MUSIC-link will be available later in 2020.

Does MUSICX have Source functionality like inbuilt calibration and optimisation?

This first release of MUSICX has focused on updating the MUSIC software architecture and ensuring that all MUSIC 6.3 functionality is maintained. As described previously, the new software provdes greater flexibility to add new functionality. We will work with the MUSIC community to identify priority areas for improvement, such as inbuilt calibration and optimization.

Like MUSIC 6.3, MUSICX supports manual calibration.

The ability to readily link to the optimization tool Insight will be available in version 2 of MUSICX.

Over time, we may look to bring elements of Source across into MUSIC X as upgrades such as the auto-calibration tool.


Specific functionality questions


Has the "edit all nodes of this type" functionality been retained?

This can be done through Edit \ Scenario Input Sets, for more information go to:

Future upgrades to MUSICX may include adding the Feature Table to support simple bulk editing, for more information on this approach go to:

Does MUSICX have the ability to model sub-timestep scale routing along MUSIC links?

Yes, MUSICX has the same capability as MUSIC 6.3.

Have extra routing models been added other than ‘none’, ‘translation’ and ‘musk-cunge’ that are in MUSIC 6.3?

There is no link routing in this first release of MUSICX. We are working to include the additional options that are currently available in Source as future upgrades.

When you run a grassed swale in MUSIC 6.3 it has 100% removal efficiency for gross pollutants. The performance of the swale is also the same, regardless of whether it is 2% grade or 15% grade. Is this fixed in MUSICX?

MUSICX has the same underlying science as MUSIC 6.3. We recognise that there are opportunities to improve the way MUSICX represents a number of treatment options. As mentioned above, we will work with the MUSIC community to identify pathways to fund further improvements to MUSICX, noting that this will also require gaining widespread support from the community for  updating the relevant algorithms. 

Does the flow transfer function within a generic node still ‘loose’ water from the model, or can I now account for this ‘lost’ water within a secondary link?

MUSICX has the same underlying science as MUSIC 6.3. The next release of MUSICX will allow you to capture lost flow using split flow functionality.

Have the source node input properties been changed from MUSIC 6.3 or are many of the Source nodes still the same (residential, commercial, industrial) with the only variation in the nodes being their name?

MUSICX has the same source node inout properties as MUSIC 6.3.

When a file is sent to a regulator to review, will it include the met-data or will they have to specify it separately?

Yes, the met data is saved within the MUSICX file.

Do secondary links exist in MUSICX?

Yes, secondary links exist in MUSICX.

Previous versions of MUSIC were not well accepted for use in WA due to unique soil conditions in the Swan Coastal Plain. Will MUSIC X be compatible for use in WA?

MUSICX can be used in any soil conditions, you just need to change the default soil properties to reflect your needs.

How does the program know how to read the rainfall xls? Does it need to be in particular column etc. or can it work it out for itself?

MUSICX supports various data formats, including csv, .txt and .dat. You need to define the data for rainfall/evapotranspiration.

Has the MUSIC 6.3 bug relating to a maximum custom storage depth within a wetland been fixed

This bug has been fixed.
