In order to runtime post-process a sloshing case (3D) different options are available to sample the free surface in distinct locations inside the domain. I am currently using OpenFOAM 2.3.0 to do some test calculations for that.
Runtime postprocessing functions can be used in the system/controlDict for fast and easy determination of the values. First option is using the "set" function. Code:
functions { Probe01 { type sets; interpolationScheme cellPoint; outputControl adjustableTime; writeInterval 0.05; setFormat raw; sets ( centerPatch { type uniform; axis xyz; start (0.000 0.000 1.000); end (0.000 0.000 2.000); nPoints 10; } ); surfaces (); fields ( alpha.water ); }; } Second option in runtime postprocessing functions is the "probe" function, where definition of single probe locations in a line can be done e.g. like this: Code:
functions { Probe02 { type probes; functionObjectLibs ("libsampling.so"); outputControl adjustableTime; writeInterval 0.05; probeLocations ( (0.000 0.000 1.000) (0.000 0.000 1.100) (0.000 0.000 1.200) (0.000 0.000 1.300) (0.000 0.000 1.400) (0.000 0.000 1.500) (0.000 0.000 1.600) (0.000 0.000 1.700) (0.000 0.000 1.800) (0.000 0.000 1.900) (0.000 0.000 2.000) ); fixedLocations false; fields ( alpha.water ); } } Therefore both ways do not seem to lead to what I am interested in, interpolating the free surface with cellPoint interpolation in locations fixed in the dynamic Mesh. Does anyone have ever thought about a solution for this problem? I guess so! I have also tried to do the same with sampleDict or probeDict postprocessing, but obviously the switch "fixedLocations false;" is not functioning their in either case. Looking very much forward for your kind help! |
