[Gmsh] Visualising point data imported from MED files

[Tomasz Koziara]

Dear Christophe,

Here is an output file with POINT1 elements exported using the previously
quoted lines of code:

https://www.dropbox.com/s/izu5o15b2ow8y9u/spring_system0rb_ele.med.gz?dl=0

And here is a stack trace of the crush which I am getting on a OS X 10.10.5
when opening this file with Gmsh 3.0.6:

https://www.dropbox.com/s/q4fdk6thv2woy7q/spring_system0rb_bug.txt.gz?dl=0

If there is a better way of annotating the MED file with elements
information in this case, I would appreciate an advice:)

Best regards,
Tomek
