EDEM 2018 includes a lot of new features and capabilities. On the visualization side, a range of enhancements have been included enabling users to make more realistic and dynamic videos. In this post I will tell you about 5 key features you might not know about and show you how to use them.
ADDING TEXTURES AND TEMPLATES
To make simulations look very realistic, it is now possible to apply a template on a particle and a texture on any geometry in the simulation. In this example I imported a template to represent rocks, then added a texture to it and added different textures to the ground and hopper elements. These changes make it much easier for a viewer to understand what is going on in the simulation and what materials different parts are made of, now it looks like the real thing!
TRACKING A GEOMETRY
Cameras now have the ability to track geometry of your choice as the simulation progresses. This is particularly helpful when your simulation includes many moving parts and you are interested in a specific one – in this example a particular bucket of a bucket elevator.
USING THE PLAYBACK SCHEDULER
This new functionality allows animations to be planned by applying Views and Analysis Configurations to timesteps as keyframes. For instance you could start with showing diameter then move to velocity and/or different view etc. The Scheduler can also be used to stop the playback at a specified time.
COLORING PARTICLES BY DIAMETER OR POSITION
Particles can now also be colored by diameter. This is very helpful when you need to analyse the effectiveness of mixing processes. You can also color particles by position along X, Y or Z coordinate. It can be useful if for example you want to keep the thickness of a bulk material under a certain level say on a conveyor.
There are 5 sensors now available in the Analyst. They can measure mass flow rate, bulk or solids density, total mass, average velocity of the particles inside the sensor and average mass or volume of one particle inside the sensor. Sensors are a great analysis tool and all the data can be exported/used for plotting graphs etc.
A couple more tips, when recording videos in EDEM make sure to select high resolution so that they look great on any device. You can play with the camera and zoom-in or use different angles to highlight different parts of your simulation and make it more dynamic. I would also recommend saving videos in AVI format to achieve the best quality. Finally, when applying texture on a geometry, make sure the size and quality of your images are sufficient. I would suggest at least 1920×1080 pixels, but everything depends on where you want to apply it on.
I hope you found these videos useful. If you have additional tips you would like to share with the EDEM user community, feel free to post them in our EDEM User Forum.
