What’s New in MedeA® version 2.14?

MedeA 2.14 provides exciting new capabilities: MedeA-Phonon now includes IR and Raman spectra simulation, MedeA-VASP 5.3 offers prediction of NMR chemical shifts, P3C (Polymer Property Prediction using Correlations) yields rapid estimation of polymer properties, and the Thermoset Builder has enhanced reporting of gelation and the extent of reaction.

Extensive enhancements to the MedeA® environment include support for large structure sets to expedite screening and high throughput calculations, conformer generation for molecules, graphics performance enhancements supporting efficient new display modes and interactive labeling. Additionally, parallel (or 'asynchronous') job execution has been added to the JobServer for structure lists and loops, facilitating use of all available computational resources so you can finish projects rapidly and efficiently with maximum coverage of materials possibilities (and free from cpu-counting licensing constraints).

MedeA 2.14 no longer requires a third party database management systems (DBMS) which streamlines installation and administration. Of course, MedeA 2.14 retains extensive DBMS support for data intensive applications.

The enhancements in the MedeA 2.14 environment, which were showcased at the Materials Design, Inc. annual user group meeting in Vienna this year, provide not only new capabilities but also a foundation for new and exciting developments which we are anticipating in coming quarters. We will be keeping you updated on these developments.

MedeA® is the leading environment for Materials Design®, modeling, and simulation for Windows and Linux environments.
