Description
The DGF parser for UGGrid and for ALUGrid does not work properly if the elements become too small. Please see the attached example with the DGF input file test.dgf. While an SGrid is created without errors from the DGF file, and a UGGrid is created without errors manually with the GridFactory, the creation via DGF fails for UGGrid.
Apparently, the second element to be created is only a line, since the upper two vertices coincide with the lower two ones when handed over to UG's InsertElement.
Uncommenting lines 56,57 yields a segfault of ALUGrid's DGF input.
Everything works well if the domain size is enlarged ((1e-4, 1e-4) for the upper right corner is enough).
