fluent 中跟踪一个点的压力,在surface中设置好点后,在surface monitor中的report type 选哪一个呀?
surface integral-facet average
再问： 我看有些资料上的例题，是用vertex average的，我查help好像一个是记录的节点值，一个记录的是单元线段中心的值，是这样吗？
再答： 你可以试试看，如果一致或相差很小很小，就无所谓了。 以下帮助供参考： 33.1.2.1. Vertex Values for Points That are Not Mesh Nodes The values of the nodes on surfaces are linearly interpolated from the mesh node data. For zone surfaces, the nodes on the surface and the zone correspond; thus, the values are identical. For surfaces that are not zone surfaces (e.g., isosurfaces, plane surfaces, etc.), the node values are interpolated from mesh nodes on the cell faces intersected by the postprocessing surface. For point surfaces, the value is interpolated from all the mesh nodes of the cell containing the point. 33.1.3.2. Facet Values on Postprocessing Surfaces Each facet on a postprocessing surface is associated with a cell. The values of a specified variable on facets are the same as the cell values of the selected variable in the associated cells (this includes iso surfaces, planes, lines, points, rakes, quadric, etc.).
