Hello I was trying out a beam problem and came upon this bug:
[image: Screenshot from 2023-04-04 13-48-55.png] On drawing the beam and plotting the shear force diagram, the result I get is: [image: simulation.png] [image: Wrong_plot.png] However, the correct plot would have been: [image: Screenshot from 2023-04-04 13-52-27.png] There are two issues with this, The support reaction are not being calculated correctly, The contribution of force due to the ramp load is wrong. I have opened an issue relating to the ramp load. I request you to take a look at it and let me know if this is an actual bug in the code. Here is the link: https://github.com/sympy/sympy/issues/25016 The code I used to get the Sympy plot results is: from sympy.physics.continuum_mechanics.beam import Beam from sympy import symbols E, I = symbols('E, I') b = Beam(6, E, I) b.apply_support(0, "pin") b.apply_support(3, "roller") b.apply_load(4, 3, 0, end=6) b.apply_load(4, 0, 1, end=3) R_0, R_3 = symbols('R_0, R_3') b.solve_for_reaction_loads(R_0, R_3) p = b.draw() p.show() b.plot_shear_force() Thanks and Regards, Abhinav Cillanki -- You received this message because you are subscribed to the Google Groups "sympy" group.
