使用双椭球热源加载时,是根据当前坐标系、热源位置和节点坐标来确定受热节点的。
如帮助文件中所说:在 LOCAL 命令中,PAR1 和 PAR2 会改变局部球坐标系的 Y、Z 轴与 X 轴的半径之比:
PAR1
Used for elliptical, spheroidal, or toroidal systems. If KCS = 1 or 2, PAR1 is the ratio of the ellipse Y-axis radius to X-axis radius (defaults to 1.0 (circle)). If KCS = 3, PAR1 is the major radius of the torus.
PAR2
Used for spheroidal systems. If KCS = 2, PAR2 = ratio of ellipse Z-axis radius to X-axis radius (defaults to 1.0 (circle)).
