Based on the model of DLA,this paper simulates the process of aggregation s growth for random walk particles from local area on two-dimension Euclidean plane.
以DLA模型为基础,模拟研究了在二维欧几里德平面上由局部区域内产生随机运动粒子的聚集生长过程,发现对于足够大的粒子运动区域和足够远的粒子源距离,凝聚集团大体上被限制在欧氏圆形面内,圆心在粒子源对称中心和种粒子的连线上,且比种粒子更加接近粒子源;凝聚集团朝各个方向的平均生长速率虽然不同,但整体仍呈分形结构。
The computer aided 3-dimensional simulation of rectangular tile coating on ship hull requires a local area on the total undevelopable surface to be approximately flattened, and the point-to-point correspondence of the plane and submarine surface to be established.
以船体表面敷设矩形柔性瓦的计算机三维仿真设计为背景,提出了不可展曲面局部区域近似展开均匀环形网格法,并以此算法为基础,在MDT平台上开发出一套工具包来完成矩形瓦敷设仿真设计。
In this paper, an explicit-implicit integration method is put forward, in which implicit integration is used in local region of structure, and explicit integration is used in .
针对实际工程问题中整体结构计算时间步长的选择往往受局部区域的材料特性、尺寸大小等因素影响的这一现象,提出了一种对结构局部区域进行隐式积分、对其余区域进行显式积分的工程实用的显隐式数值积分方法,这种积分格式相对于显式积分格式而言,能显著提高整体结构的计算速度。
