• Segment :math:`\text{AB}` is divided into 10 elements of the same length (10.). (One item would be sufficient.)

• 5 identical calculations are carried out successively on this mesh with 4 different models:

• with 10 POU_D_E elements

• with 10 POU_D_T elements

• with 10 POU_D_TG elements

• with 10 POU_D_EM elements

• with 10 POU_D_TGM elements
