Hello
How is everyone doing??
So,Im doing a OpenFoam when my geometry is based on parallel boxes,with a retangular base,as shown :

cellSet heater new boxToCell (0.049925 0.050 0 ) (0.155925 0.156 0.004)
cellSet heater add boxToCell (0.049925 0.050 0.004)(0.155925 0.052 0.018) //1
cellSet heater add boxToCell (0.049925 0.058 0.004)(0.155925 0.060 0.018) //2
cellSet heater add boxToCell (0.049925 0.066 0.004)(0.155925 0.068 0.018) //3
cellSet heater add boxToCell (0.049925 0.074 0.004)(0.155925 0.076 0.018) //4
cellSet heater add boxToCell (0.049925 0.082 0.004)(0.155925 0.084 0.018) //5
cellSet heater add boxToCell (0.049925 0.090 0.004)(0.155925 0.092 0.018) //6
cellSet heater add boxToCell (0.049925 0.098 0.004)(0.155925 0.100 0.018) //7
cellSet heater add boxToCell (0.049925 0.106 0.004)(0.155925 0.108 0.018) //8
cellSet heater add boxToCell (0.049925 0.114 0.004)(0.155925 0.116 0.018) //9
cellSet heater add boxToCell (0.049925 0.122 0.004)(0.155925 0.124 0.018) //10
cellSet heater add boxToCell (0.049925 0.130 0.004)(0.155925 0.132 0.018) //11
cellSet heater add boxToCell (0.049925 0.138 0.004)(0.155925 0.140 0.018) //12
cellSet heater add boxToCell (0.049925 0.146 0.004)(0.155925 0.148 0.018) //13
cellSet heater add boxToCell (0.049925 0.154 0.004)(0.155925 0.156 0.018) //14
cellZoneSet heater new setToCellZone heater


THe problem is that I need to separate it in 2 regions,the parallel boxes ( 1 to 14) need to be separated from the base,but Im having problem because the command boxToCell seems to be used only when the boxes are connected to the main on(the one without any number)
How I am supposed to make a region between these boxes??Please help me

Dear,
look carefully at chtmultiRegion tutorial, you will find how to recall the space between box, in brief
you need a create a CellSet, then add to this CellSet all present boxes, then invert cellSet to choose remain cells

consider you have two sets A and B, which B is a sub-set of A, when you use invert B,
means all cells which are in A but not in B

look at tutorials its easier way to find each dictionary how works , however you can use command remove, to remove one cellSet, or easily you can go to polyMesh in setSet folder and see whats your cellSet name is and remove it manually
