3. Modeling A#
3.1. Characteristics of modeling#
Segment \(\text{AB}\) 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
