Your XPStorm modeling package can be expanded to meet your needs by adding the following optional components:
xp2D gives you the power to analyze and predict potential flood extents, depth and velocity and accurately model the interaction of surface and underground systems in an integrated 1D/2D modeling environment. The software can also be effectively used to simulate and analyze tidal surges, dam breaks and breaches on sewer networks.
In addition, xp2D is an excellent tool to evaluate flood hazards and evacuation route time to inundation.
GPU Modules for xp2d
The GPU Module enables XPStorm users to leverage graphics processing unit (GPU) hardware to rapidly accelerate simulations. XPStorm is compatible with Nvidia GPUs to provide a significant reduction in time to complete 1D and 2D simulations.
By leveraging the latest TUFLOW analysis engine, the xp2D Extreme engine, powered with GPU Module, will now support 1D and 2D accelerated simulations on the latest Nvidia hardware.
The GPU platform can accelerate application workflows across the thousands of GPU cores in parallel threads, resulting in shorter run times. XPStorm now provides 2D-only acceleration that reduces runtimes from hours down to minutes. This update improves the level of efficiency for modeling workflows allowing for quick analysis and results from event simulation. Now you can get the information you need from your model, when you need it.
Multiple Domain for xp2D
The Multiple Domain add-on feature for xp2D allows you to more efficiently utilize your 2D cells, and provides a way to focus analysis where it is needed most. It allows several domains to be added to a single model, each with its own grid extents, time step, grid cell sizes and orientation.
Multiple 2D Domains are often used to reduce the number of cells in a 2D modeling project. Large cell sizes are used in areas where fine detail is not required or where a large area is to be modeled. Small grid sizes provide more detailed analysis of varying terrain, channels and urban areas.
For example, a cell size of 1-2 meters could be used for the flow in a narrow channel of say 10m wide and then a separate 2D grid of 10 meters could be used for a nearby floodplain. Flow from one 2D Domain can be joined to another with the 2D/2D Interface polyline tool that exchanges flows between the two distinct 2D Grid Extents.
With xpviewer Reader, your clients and other stakeholders associated with your project will have the ability to view and interrogate an encrypted version of your XPStorm models. The xpviewer program allows all software functions except the ability to change, export and solve the model. Therefore your stakeholders can view model animations, query and print the model results and participate in the model development and approval process without being required to purchase a license from Innovyze.
This is an excellent tool for those customers who wish to share their model with others within or without the organization who do not already own a license of the software, but wish to view the model(s) results. Since the model cannot be changed or resolved with xpviewer Reader the integrity and security of the created model is preserved.
It is also excellent for reviewing agencies who wish to view and query every element of a model and its results but don't wish to take on the modeling work itself.
Real Time Control
Real Time Control (RTC) elements such as regulators, bendable weirs, and telemetry-controlled pumps are part of XPStorm. These hydraulic elements allow changes to model elements in real time (evaluated at every time step) based on defined depths of flow in any node in the model. Many control strategies can be evaluated in the program by using a combination of rating curves and these RTC elements. However, complex situations involving multiple sensors and Boolean logic are only possible by expanding XPStorm with our RTC add-on module. This powerful add-on module extends the existing depth-only RTC to a comprehensive management and design tool.
The RTC sensors can also include any combination of date/time, velocity, flow and water levels and depths at nodes, conduits, pumps, orifices, and weirs. The values of the sensors can be compared to static values and with each other using typical Boolean logic and mathematical operators. For example, a control can be activated if the water level in location A is greater than location B by 2.3 feet.
Many dependent hydraulic parameters for the selected objects can be controlled. The parameters that can be modified include: flow, roughness, diameter, water depths, pump on/off levels, well volume and speed factor, weir crest and surface elevation, discharge coefficient and length, and orifice area coefficient.
Additional control properties include Start and Stop time of the control, ramp times and maximum and minimum values. Operators can be concatenated with Boolean operators, and parameters can be compared with other sensors or with absolute values. Real time control can be activated during certain hours of the day, odd/even days, days of the week, months of the year and control can turn on and/or off over a user-defined time period.
WSPG (Water Surface Pressure Gradient) is a hydraulic analysis that computes uniform and non-uniform steady flow water surface profiles and pressure gradients in a network of open channels and closed conduits. This tool, originally developed by Los Angeles County, has been upgraded by Innovyze and is available as an add-on module to XPStorm. Applications include engineered channel design, urban drainage analysis and minor hydraulic loss analysis.
After designing the model using the steady state WSPG solution, the model can be switched to a full dynamic analysis in XPStorm. This combination of solutions allows the modeler to have confidence that the proposed design maintains the hydraulic grade line to acceptable levels and that storage facilities are sized correctly for major events.
Digital Terrain Model + xp2D
The Digital Terrain Model (DTM) module for XPStorm allows the graphical interface to create and contain an embedded DTM or surface model. The embedded triangular irregular network (TIN) can be created from manhole elevations, a file containing a series of X Y Z and (optional) string data or directly read from popular terrain modeling packages.
With the surface model incorporated into the project the user can create perspective views, drape geo-referenced images, obtain ground elevations automatically for nodes, cut cross sections for natural channels and view flooded results in 3D.
DTM Module for XPStorm allows the following:
- import of 12d TIN and triangulate X Y Z input
- shading of the TIN to graphically show elevation
- display and labeling of contours
- adjustment of the TIN transparency and reveal contours
- addition of elevation to the status bar to track the easting, northing and elevation of the mouse location
- display of a cross section profile by drawing a polyline
- automatic calculation of natural channel cross sections for links
- automatic calculation of node ground elevations and inverts
- automatic generation of 2D grid elevations (using the xp2D Module)
This component of XPStorm adds the ability to generate both point and non-point pollutant loads, and to route these pollutants through the drainage network.
This drainage network can also include the river system and therefore allows the user to analyze the effect of Sanitary Sewer Overflows (SSOs) and Combined Sewer Overflows (CSOs) on the water quality of the natural receiving water system.
The water quality module also allows the routing of these pollutants in the Runoff or the Hydraulics layer with the latter coupling the full Dynamic Wave solution and pollutant transport by convection.
This module allows export of your XPStorm model to an EPA SWMM5 format input file and import from an EPA SWMM5 input file into XPStorm. A file xx.inp is created where xx = XPStorm file name in the same folder as the XPStorm file.
Note: Users should be aware that an XPStorm model may contain many features note supported in EPA SWMM5. In addition, the SWMM5 calculation engine is different than the proprietary XPStorm calculation engine. Accordingly, it is not reasonable to expect that the SWMM5 software will yield identical results as an XPStorm simulation. However, the bulk of the data is transferable.
EPA SWMM 4.2, 4.4 and 5 files may be imported or converted to our generic XPX file for import using our standalone EPA-SWMM Data File Reader.
