The Changing Face of Simulation
By Joy LePree – Simulation software and its capabilities have come a long way in recent years. The latest versions include easier-to-use and more advanced features, increased computing speeds and simplified integration with other simulation programs, as well as data analytics and Industry 4.0 technologies. These modern features allow today’s simulation tools to be employed in a variety of applications throughout the lifecycle of a plant.

As a result, chemical processors are using simulation not only for design and optimization tasks, but also for other challenges, such as increasing safety and avoiding operational risk, achieving sustainability goals and training employees.

While simulation has become the de facto method for designing and optimizing processes in the chemical process industries (CPI), for many years, users didn’t apply the technology to other types of analysis, such as overall profitability, safety issues or smaller engineering problems, because it took too long to get an answer or because the simulators were too difficult to set up and use. As a result, some software providers have built solutions with lower-fidelity models that are easier to build and use. Meanwhile, other providers have taken steps to increase speed of calculations and simplify the use of rigorous process simulators.

Another change Chemstations has made is to increase the computing speed of its rigorous process simulator by taking advantage of parallel processing, which uses all available computing cores. “This means that instead of using just one core of the user’s computer, we can spread the workload across as many cores as are available, which will speed the process considerably,” explains Brown. While the initial intent of the improved calculation time was to allow faster execution of large optimization projects, the increased speed opens the door for simulation of smaller-scale projects and “what-if” studies. more>

Simulation Takes on Bigger Roles in Product Development

By Rob Spiegel – The real world isn’t what it used to be when it comes to testing. Simulation has created a world of new product testing that puts products through scenarios that cannot be duplicated by prototypes in the real world.

Instead of just testing an actual part physically, simulation can test an entire complex product – like a car – and see how each part performs in conjunction with the entire product – a form of accurate testing that can’t be done in the real world.

The exception is with composites and some 3D-printed parts. There is not enough data on the new materials and 3D-printed shapes to provide accurate simulation. That’s temporary, however. The data from the physical testing of composites and 3D shapes are getting fed into simulation programs so those programs can begin to include new materials and shapes into the digital world of simulation.

Simulation used to be a side function, something done after preliminary design to see how the product performs in the real world. Simulation has moved to the center of the process so the product’s performance can be evaluated as it is being designed. more> https://goo.gl/72FE3N

The Underestimated Role of Simulation in Architecture, Engineering and Construction

By Deepak Datye – We need to think about product, nature, and life together not only to allow for creating innovative designs, but also to provide optimal functionality, ensure safety, and safeguard sustainability, for ecological well-being. Product, nature, and life, hence, need to play a conjoined role during planning for large engineering projects such as city developments, large transportation projects, as well as dam and irrigation works.

This will need to be done through realistic simulations that take into account precise geometry and material properties, realistic representations of physical and natural processes, and rational predictions of experiences by people.

Representing products as they are has become fairly widespread and well understood. Engineers are able to create a detailed geometrical representation of the product, be it a doubly curved concrete superstructure, a curved Plexiglas window on an undersea hotel structure, sound absorbing acoustic panels inside auditoriums, or roof tiles and linings in railroad tunnels.

The key however to understand how an entire structure will behave in real life is to accurately represent the material properties it’s composed of, including the response behavior of the material to changes in stress and temperature over time, and material degradation due to interactions with humans and natural surroundings. more> https://goo.gl/WNIQpj

BOOK REVIEW

Consciousness and the Social Brain, Author: Michael Graziano.

By Michael Graziano – Imagine a future in which your mind never dies. When your body begins to fail, a machine scans your brain in enough detail to capture its unique wiring. A computer system uses that data to simulate your brain.

It won’t need to replicate every last detail. Like the phonograph, it will strip away the irrelevant physical structures, leaving only the essence of the patterns. And then there is a second you, with your memories, your emotions, your way of thinking and making decisions, translated onto computer hardware as easily as we copy a text file these days.

That second version of you could live in a simulated world and hardly know the difference. You could walk around a simulated city street, feel a cool breeze, eat at a café, talk to other simulated people, play games, watch movies, enjoy yourself. Pain and disease would be programmed out of existence.

Your connectome, simulated in a computer, would recreate your conscious mind. Of course, nobody knows if the connectome really does contain all the essential information about the mind. Some of it might be encoded in other ways. Hormones can diffuse through the brain. Signals can combine and interact through other means besides synaptic connections. more> https://goo.gl/7xUMFf

Simulating the birth of a planet

R&D Mag – Over the past few decades, the hunt for extrasolar planets has yielded incredible discoveries, and now planetary researchers have a new tool–simulated models of how planets are born.

Sally Dodson Robinson, astronomer, and her team of researchers at the University of Texas at Austin are modeling and simulating these protostellar disks. The simulations model important factors such as the turbulence and temperature of the disk, which affect how and where planets form. In a disk that is too turbulent, the particles move too fast and bounce off each other. Less turbulence means a greater chance for them to collide and stick together.

In 1988, we knew of one solitary extrasolar planet. In 2012, we know of almost 2,400 awaiting confirmation. more> http://tinyurl.com/9fsb5ba
