【摘要】：基于網(wǎng)格切割思想,發(fā)展了二維/三維混合網(wǎng)格條件下的單元相交算法,可精確計(jì)算任意兩個(gè)多邊形/多面體的交集。在此基礎(chǔ)上,實(shí)現(xiàn)了基于單元相交(CIB/DC)的精確守恒插值算法。二維和三維驗(yàn)證算例表明,該方法能夠保證插值過(guò)程中計(jì)算域內(nèi)物理量的嚴(yán)格守恒,且具有比常規(guī)二階插值更高的精度。
[Abstract]:Based on the idea of mesh cutting, the element intersection algorithm under the condition of 2D / 3D hybrid mesh is developed, which can accurately calculate the intersection of any two polygons / polyhedrons. On this basis, an accurate conservation interpolation algorithm based on intersecting CIB-DC is implemented. Two and three dimensional verification examples show that the proposed method can guarantee the strict conservation of the physical quantities in the computational domain in the interpolation process and has a higher accuracy than that of the conventional second-order interpolation.
