Should I take out ps1? Did u mean that? I'm really sorry for asking this.

Robert, Thanks a lot for your reply. ps0 = [[0.0, 1.0, 0.0], [ 0.0, 1.0, 0.0]] # <- starting points ps1 = [[5.0, 1.0, 0.0], [ 0.0, 1.0, 1.0]] # <- ending points I know the meaning of it. My question was how to plot the displacement at y=1 from x=0 to x=5.
This is done only by (assuming you want x in [0, 5], y = 1, z = 0):
ps0 = [[0.0, 1.0, 0.0]] ps1 = [[5.0, 1.0, 0.0]]
You do not need the second pair of points.
Does it help?

Sorry for asking too my questions. I am new to SfePy.

Robert, I changed " stiffness_from_youngpoisson(2, young, poisson)

Now it's fixed. (Output is attached, Result).
But I tried to plot the displacement, strain and stress only u1 and
u2
are
on the plot, as per my understanding u1 and u2 are displacements in x and y directions. How do I plot u3 ( displacement in the z direction). I referred
on line 43 of Cuboid_graph.py, change
for ic in range(vals.shape[1] - 1):to
for ic in range(vals.shape[1]):its2D_interactive and made changes according to my problem definition. Also at the top surface I want to plot the displacement from x=0 to x=5 but in the plot it is showing only from x=0 to x=1.
The lines
ps0 = [[0.0, 1.0, 0.0], [ 0.0, 1.0, 0.0]] # <- starting points ps1 = [[5.0, 1.0, 0.0], [ 0.0, 1.0, 1.0]] # <- ending pointsmean, that the first probe goes from [0.0, 1.0, 0.0] to [5.0, 1.0, 0.0], and the second from [ 0.0, 1.0, 0.0] to [ 0.0, 1.0, 1.0] - it corresponds to the xlabels in the images. Try fixing that.

Could you please also help me to fix this aswell?
Thanks in advance, Nayan

Hi Nayan,
when strange things happen, it is usually worth to check your region definitions.
Use:
./simple.py Cuboid_1.py --save-regions-as-groups
and fix the bottom region:
'Bottom' : ('vertices in (y<=-0.9999)', 'facet'),Also, in Cuboid_2.py, replace
stiffness_from_youngpoisson(2, young, poisson)
by (it's 3D problem)
stiffness_from_youngpoisson(3, young, poisson)
Note also, that having the code in the module namespace causes it to
be
called also before running the simulation (on input file import).
Let me know if that helps.

Hi Robert, I calculated displacement, strain and stress for the block under area loading. I am not convinced with the answer. Displacement and strain are maximum at the corners, but stress is maximum in the middle. I think my problem description file is completely messed up.Is it?
Also when I try plot displacement, strain and stress components, one of
