November 2016 - New Interface with LS-DYNA Announced

Dynamic Design Solutions announces an interface and driver for the LS-DYNA finite element program.  The new interface and driver will become available as an optional module in the next major release of FEMtools. This will be the first commercially available solution for Verification and Validation of LS-DYNA models using modal test data.

LS-DYNA is a general-purpose finite element program capable of simulating complex real world problems that is developed by Livermore Software Technology Corporation (LSTC). It is used by the automobile, aerospace, construction, military, manufacturing, and bio-engineering industries. The code's origins lie in highly nonlinear, transient dynamic finite element analysis using explicit time integration. LS-DYNA's potential applications are numerous and can be tailored to many fields. It is one of the most flexible finite element analysis software packages available.

The new LS-DYNA interface program will be capable of importing an input file as well as various types of results files. The bi-directional interface uses a new innovative mechanism to maintain complete fidelity between the originally imported and modified models. A driver script is included to make changes to virtually any input parameter of the finite element model, and launch the LS-DYNA solver for re-analysis.  The full range of FEMtools applications, like test planning, correlation with test, sensitivity analysis, model updating and design space exploration will be supported.

The Shanghai Academy of Spaceflight Technology (SAST) is one of the key bases of Chinese spaceflight industry. Their aerospace products involve a series of launch vehicles, applications satellites, manned spaceship, deep space exploration and lunar rovers. One of their divisions, the Shanghai Institute of Aerospace Systems Engineering (SIASE) is a research institute and main developing unit of launch vehicles in China.

The China Electronic Technology Group Corporation (CETE) is responsible for China's communications systems equipment, radar detection equipment, solar cells and a large number of key components of the development task. Its Shijiazhuang Communication Measurement and Control Technology Research Institute is the first telecommunications technology research institute in China.

Both SIASE and CETE chose FEMtools for validation & verification of finite element models, optimization of test plans, and finite element model updating with test data.

From the design and analysis of digital prototypes to test, FEMtools is widely used during the whole process. FEMtools ensures that the simplified finite element model has the same stiffness and mass as the original model. The design can be checked and optimized with this accurate FE model. Before testing, the number of sensors and location are optimized. After test, FE models are updated with test data. Using FEMtools scripts, a CAE automation process is developed.
