[Getdp] different results when considering surfaces

[Andre Antunes]

I have two identical meshes, with the difference that in one of them, all surface elements (triangles) have been removed.

It surprised me that the solution resulting from a simple (quasi-static) vector potential is different in both situations, since the nodes and degrees of freedom are exactly the same for both cases.

Why would the presence of triangle elements change the result?

I'm attaching the corresponding .pro files. 

a working example is set here:

Best regards, 
Andre
