关于重叠网格的几点疑问,想请教一下相关大神
-
@gentle local和remote是
inverseDistance
插值方法输出的信息,具体的我也不是很清楚,是它内部的一个插值过程,源代码在/src/overset/cellCellStencil/inverseDistance/inverseDistanceCellCellStencil.C
,如果只是使用重叠网格的应用,这个我认为可以暂时不管它。如果不对,应该是网格的问题,我是用STAR CCM+
或者Pointwise + cfmesh
准备重叠网格的,没有问题,也没关心过这个local和remote,你可以参考一下。 -
@我是河滩 两个软件都需要额外操作才能正确显示重叠网格。tecplot可以参考链接
http://2016.oversetgridsymposium.org/assets/presentations/tutorials/ogs2016-fowler-tecplot.pptx
和https://fun3d.larc.nasa.gov/session9_july.pdf
,paraview可以参考https://twitter.com/openfoam/status/883256187390750720
,里面说了The cellTypes field can be used to subset only the active set of cells - in ParaFoam/ParaView: Filter->Threshold
,最小值0,最大值1。 -
@我是河滩 There is no Chinese input tool in my Linux workstation, so I replied this in Eng. Take
plus 1812
version for instance. It is simple if you prefer to writecellTypes
field in the solver ofoverPotentialFoam
, just addmesh.write()
to the end ofoverPotentialFoam.C
, i.e.,p.write(); } mesh.write(); // Add this runTime.functionObjects().end();
mesh.write()
will call the member functionFoam::dynamicOversetFvMesh::writeObject()
wherecellTypes
andzoneID
fields have been defined. They will be written to0
time folder inoverPotentialFoam
.
