Hi Nima,
the first problem is that Plane Surface 65 is partially superposed to Plane
Surface 88.
It's much simpler to create the ferrite by extruding down the coil, like I
started to do in the attached file.
Then to build the conductor over the coil, you must start from the existing surfaces of the coil, to again avoid to have
partially superposed surfaces...
Regards,
Dave
Dear Sir/Madam
I am trying to model Induction Heating problem and I am using GMSH 2.5
(windows) to define and mesh my geometry. As you
know since further more I will need curl of magnetic potential field as the
base for solving PDEs, I want my mesh to be
as accurate and fine as possible.
However as I try to mesh it it gives me self intersecting surfaces error, due
to the fact that my surrounding cube has
two holes which one of them consists of two bodies connecting to each
other(different materials).
Could you please take a look at my attached .geo file and let me know how I can
solve this problem?
Many thanks in advance.
Kind Regards,
Nima
