Abstract
유한차분법에 바탕을 둔 수치모델링은 컴퓨터기술의 발전과 함께 다양하게 이용되고 있다. 하지만 대용량의 컴퓨팅 리소스를 필요로 하는 문제를 지니고 있다. 이러한 한계를 극복하기 위해 본 연구에서는 로그격자와 영역확장법을 함께 적용하여 수치모델링 알고리즘을 제안하였다. 기존의 일반적인 등격자 유한차분법과 비교를 통해 알고리즘의 타당성 및 정확성을 검증하였으며, 수치예제를 통해 새롭게 제시된 알고리즘의 계산 효율성을 확인하였다.

Numerical modeling based on the finite difference method has been widely used with improved computer technology. However, high-capacity computing resources are required for this technique. To overcome this limitation, we propose an algorithm the employs a logarithmic grid in conjunction with the expanding domain method. The proposed algorithm was verified through comparison with numerical results obtained with a conventional method. The results confirmed that our algorithm can improve computational efficiency.
