Hello, While solving a simple problem using FE_Q_DG0 elements, I found that the output data vector (created by DataOut.add_data_vector) has non-unique values for the same point. Attached is an example .pvd file. Here, there are two points of same coordinates (0.1,0.95,0), and the pressure values of the two points are different.
I solved the same problem with FE_Q elements. Then the output file also contains two points of same coordinates (I don't know why), but their solution values are identical. Could somebody explain why there are two points of same coordinates and why their solution vales are different only in FE_Q_DG0 elements?
