• Serbian researchers have developed a new technique at CESGA under a cooperation agreement signed with the University of Novi Sad.
• It could be much faster and more accurate than previous modeling methods used in civil engineering structures, bridges and very tall buildings, especially.

The Harmonic coupled finite-strip method (HCFSM) is an absolutely new computational method for solving mechanical problems related to modeling of structures in civil engineering. Specific for the design of high structures, bridges and building components, such as large steel beams, the new method is much faster and more accurate so far, and means progress in the design of structures in Civil Engineering, and its validity was demonstrated in research being done by scientists at the University of Novi Sad, Serbia, at the Supercomputing Center of Galicia, CESGA.

This was announced today at CESGA by Professor Lazar Stricevic, Faculty of Science Technical University of Novi Sad, Serbia, (http://www.uns.ac.rs/en/) during a conference called "The Harmonic Coupled Finite-Strip Method Implementation," in which he presented his research and the progress made so far. Prof. Stričevid is conducting a research under a collaboration agreement signed between CESGA and the University of Novi Sad.

Currently on CESGA's supercomputers, he is testing the Prototype Implementation of The Harmonic coupled finite-strip method (HCFSM) to perform calculations on longitudinal structures by calculating each "band" on a single processor, thereby allowing very fast calculations and can be divided into a system like Finisterrae supercomputer while using about 200 processors.

The research objective is to reduce the runtime of the program called FSMNE, developed by Professor Milašinovid at the University of Novi Sad, through parallelization. This involves conducting a test of the prototype Scalability program in a large number of processors, a performance test run on IA-64 and x86 to compare and identify computational limits of the program.

HCFSM: faster, more accurate

Finite Band Method, Finite-Strip Method (FSM) is a numerical method derived Finite Element Method, Finite-element method (FEM), which are used for determining the effects of loads on physical structures. The stiffness matrix of the structure is calculated together on all sets of terms, so that is even somewhat more complex, it's more accurate than other versions of the FSM.

By introducing the geometric data structure, materials and features of the vectors increase over their forces, the program calculates the stiffness matrix of the system (voltage) and the displacement of the system matrix (deformation).

The advantages of the new method being tested on the Finisterrae and SVG supercomputers at CESGA, is that it requires fewer equations for resolution, but they are more complex. Thus the Harmonic coupled finite-strip method (HCFSM) is faster and more accurate than other methods such as FEM, but it is especially suitable for the design of bridges and high structures, and to design fundamental construction components such as steel beams, for example.
