Elastic Wave Propagation Simulation System Based On Parallel Processing Architecture
نویسنده
چکیده
The authors developed numerical methods based on Local Interaction Simulation Approach (LISA) and Elastodynamic Finite Integration Technique (EFIT) for simulation of elastic wave propagation in structures. The methods have been implemented in the simulation framework using parallel processing architecture Computer Unified Device Architecture (CUDA) offered by graphical processing units (GPUs). The proposed approach enables calculation of large models (approx. 35-40 mln DOFs) and reduces calculation time hundreds times comparing to the same algorithms implemented using standard processors. Developed numerical methods have been coupled with FE modelling of piezoelectric transducers. Simulation environment has been integrated with the measurement hardware and allows for using simulation-based settings directly in measurement. Obtained experimental data can be correlated with simulation-based one.

Three-dimensional pseudospectral modeling for a realistic scale problem is still computationally very intensive, even when using current powerful computers. To overcome this, we have developed a parallel pseudospectral code for calculating the 3-D wavefield by concurrent use of a number of processors. The parallel algorithm is based on a partition of the computational domain, where the field qu...

Among different discretization approaches, Finite Difference Method (FDM) is widely used for acoustic and elastic full-wave form modeling. An inevitable deficit of the technique, however, is its sever requirement to computational resources. A promising solution is parallelization, where the problem is broken into several segments, and the calculations are distributed over different processors. ...
