Edinburgh, Scotland, 2009/08/27 - DEM Solutions, experts in particle simulation solutions, announces the release of EDEM 2.2--the latest version of their multi-purpose modeling software used to simulate and optimize bulk particle handling and processing operations.
Recent versions of the software have seen the addition of a number of cutting edge features--driven by customer input and collaboration—that open the door to more sophisticated particle simulations. The latest version of EDEM includes a number of enhancements to help the user configure exactly the data they require for analysis--improving productivity and ultimately maximizing the time spent solving engineering problems.
Reduced file size = less storage, bigger simulations and faster analysis
When EDEM users routinely save all simulation data there’s no need to specify, in advance, which data is to be analyzed. However, as EDEM gives users the capability to run ever-larger simulations the resulting file sizes have also increased—along with a need for increased data storage capacity. EDEM 2.2 still has the option to save the full dataset, for use as restore points, but now includes the ability to selectively save sub-sets of the results data. Selecting only those sub-sets required for analysis can substantially reduce the file size. This gives users the flexibility to store a greater number of simulations—even large-scale simulations—for a given storage capacity.
“With the new sub-set save option, we don’t have to increase storage capacity to handle noncritical data, and—with smaller files—it takes less time to extract and visualize the simulation.”
Time synchronization = flexibility in linking to external data sources
Those users who run EDEM simulations along with other external data sources will now have the option to synchronize time in EDEM 2.2 with their external time settings. This is good news for users who run simulations with pre-defined geometry dynamics, external dynamics coupling, or field data linked to an external data source.
When saving an EDEM 2.2 simulation deck, users can now reset the elapsed simulation time to zero-- or any other value—synchronizing the new deck with the desired reference start time. All graphs produced from the results using the new simulation deck will read more easily--with axis labels generated from the user specified time.
“The ability to synchronize start times with our external data sources saves us time on cross data analysis--and even gives us graphs that enhance our project presentation.”
New Mass Generation Rate tool = control over mass/volume distribution
EDEM users who need their simulations to replicate specific mass flow rates--or fill a volume with a given total mass—can better define and control those issues with the new Mass Generation Rate feature in EDEM 2.2. This feature, part of EDEM’s “Particle Factory” will be valuable to users who design Bulk Solids Transfer systems—especially Conveyor Transfer Points.
With the new Mass Generation Rate feature EDEM 2.2 users can specify initial conditions which naturally match the most frequently-simulated operating condition—mass of particles per unit time. By choosing an appropriate initial particle velocity and defining the mass, users create the desired mass flow rate. Then, as they run simulations, The Particle Factory will monitor both the total mass and the percent of match to the desired mass distribution and target volume. With EDEM’s existing virtual geometry capability, that target volume can be any shape or equipment geometry imported from CAD.
“The Mass Generation Rate feature lets us run multiple bulk particle flow profiles on our virtual prototypes. It gives us info on particle mass distribution, as well as particle numbers—so we can quickly zero in on our most effective designs.”
User-defined shapes for “binning” particle data = more flexibility in targeted analysis of material behavior
EDEM’s existing post-processing tools allow users to calculate the bulk material characteristics of specific particles during a simulation run—by capturing them a “bin” at any location in the simulation. With EDEM 2.2 the bin can be ANY shape (not just cubic) and can link to any piece of physical geometry—such as a moving excavator bucket, or the rotating disc of a fertilizer spreader—gathering statistics over time.
“Being able to design particle data bins that mimic the shape of equipment or entirely fill a given geometry has given us even more confidence in our results—now we can spot check exactly where and when we need it.”
“Flexibility and efficiency in model set-up, simulation, and data analysis are always our goal”, says John Favier, CEO of DEM Solutions, “because as DEM becomes a commonly-used tool in the solution of particle problems, engineers are looking for more--ease-of-use combined with the ability to customize. The new features and capability in EDEM 2.2 support the focus of our customers-- by helping them fully exploit the value of particle simulation we help them deliver the best possible engineering solutions”
