Regarding box keyword in toposet Dict!
To simulate flow induced by plasma actuator solid-fluid domain is necessary, hence in my previous post some foamers suggested me to learn chtMultiRegionFoam/chtmultiRegionSimpleFoam. Today I am practising multi region heat transfer related tutorials, but I don't understand following keyword used in those tutorials.....found in toposet dict.
// Heater { name heater; type cellSet; action new; source boxToCell; sourceInfo { box (-0.01001 0 -100 )(0.01001 0.00999 100); } } I want to know the details about the numbers at right side of box keyword, are they co-ordinates of box of a specific solid/fluid (in example, that box defines a heater)? Thanks in advance. update: I think those are the indication of box co-ordinates, as stated here, if so...then the number '100' is confusing as in blockmeshDict I found the domain size is 0.2X0.08X0.1 (in meter) with 30X10X10 cells in xyz directions. If those are coordinates then 100 (z value) goes outside of domain!!!! |
those points define two heads of main diameter of box,
so those cell which are placed on this region will be captured as cellSet |

as i said, if you want to define a box! you need to define two points
these points are two heads of main diameter of the box. if you want to define your box in domain :), then define these points in domian :D |

box (-0.01001 0 -100 )(0.01001 0.00999 100); so in z direction the box goes outside of domain?? Actually I am confused about the z location of box i.e. -100 t0 100 |
well Mominul:D
its OK! consider an imaginary box larger than! domain what happens? nothing special! that part of domain which are in that box are selected! |
