New Software Release: MedeA® 2.21 Superior by Design

 

 

Materials Design, Inc. announces the release of MedeA® version 2.21. With MedeA® software version 2.21, users will now be able to screen hundreds to thousands of structures using HT-Launchpad and HT-Descriptors, run VASP simulations using GPUs, build involved multi-component systems with increased control on local ordering using the Amorphous Materials builder, and enjoy general productivity and efficiency enhancements in the ensemble of the various tools available in MedeA®. MedeA® runs natively in 64-bit mode both on Windows and Linux operating systems. 

 

The release of MedeA® 2.21 allows the user to:

  • Benefit further from High Throughput calculations, using readily available or user-defined descriptors to identify structures that best match certain criteria. The use of Structure Lists with the HT-Descriptor module and MedeA® Flowcharts reduces the need for human intervention while maximizing the use of available resources (databases, computing power).
  • Enjoy creating models easily and efficiently, combining building automation with high flexibility and control over the systems’ details, through the various extensions and additions of the building tools. Enhancements of the Amorphous Materials builder facilitate the building and handling of thermosets, fluid-solid interfaces or highly ordered systems.
  • Use forcefield extensions and improvements which add on the existing capabilities of studying systems ranging from alloys to multi-functional organic molecules using forcefield methods (molecular dynamics and Monte Carlo)

"This release of MedeA® provides direct access to flexible high throughput simulation so that researchers can screen and develop materials and compositions efficiently,” says Clive Freeman, CEO of Materials Design. “Materials Design® concentrates on providing access to the best computational methods, and MedeA®’s HT capabilities are the natural extension of this focus and dedication.”

MedeA® is the leading professional software environment for atomistic materials modeling used at more than 400 customer sites worldwide. Scientists and engineers in industry and research institutions use MedeA® to understand complex processes such as mechanical failure, diffusion in batteries, and catalytic reactions; and to compute materials properties efficiently and systematically. MedeA® helps to create better products while saving valuable research and development time and cost.

MedeA® integrates world-leading structural databases (i.e., totaling over 980,000 entries), electronic structure programs, molecular dynamics and Monte Carlo methods with a host of powerful building, editing, and analysis tools in a unified environment thus allowing elaborate workflows to be used in a most efficient, easy to implement and reproducible manner. Its innovative high-throughput (HT) capabilities enable the full exploitation of increasingly available computing power.

MedeA® 2.21 - New Capabilities

The new release, MedeA® 2.21, offers a range of new capabilities and enhancements as follows:                                                                                                                                                            MedeA®-HT-Descriptor:

- This new capability enables the creation of a great manifold of materials descriptors using chemical and topological properties in combination with computed properties, thus enabling high-throughput screening. For example, a descriptor can be defined combining in a single functional expression the mass density, the degree of space filling, and the computed bulk modulus. This descriptor can then be applied to structure lists either interactively for short lists or in the form of a stage in MedeA® Flowcharts to process long lists in background jobs. New descriptors can be created using previously defined descriptors as arguments in a recursive form. Collections of descriptors can be archived in catalogs and used subsequently in systematic high-throughput screening. MedeA®-HT-Descriptor is supported by convenient interactive tools for editing, displaying, sorting, and exporting structure lists with descriptors.
