Open ghost opened 4 years ago
I have met the same question when I want to set physical line groups after a series of Boolean union and difference. I wonder if there is a solution for this problem after these years...
is this package still maintained? looks like the boolean issue for gmsh>=4.8.4 (#519) havn't been fixed for a long time
I intend to get the union of few rectangles and still be able to mark the some of their lines as physical line.
I have noticed that in order to get the union / merge rectangles I need to use the OpenCascade engine and use boolean_union. At the same time, the object Rectangle that I create does not give me access to its lines to mark. Here is MWE.
Ideally, I could mark one of the lines in
heat_exchanger
as wellIs there any way around this?
