I need to apply boundary condition after reading data from .txt file. Any clue, how can I apply? from dolfin import * import matplotlib.pyplot as plt from dolfin import * mesh = UniSquareMesh(10,10) V = VectorFunctionSpace(mesh, "Lagrange", 1) left = CompiledSubDomain("near(x[1], side) && on_b…

Hi, I have tried applying the same logic to my problem but getting some error while assigning to ux in the loop (AttributeError: ‘function’ object has no attribute ‘setValueLocal’): Please find MWC from dolfin import * import numpy as np #fname = 'exdata.txt'; #values_x = np.loadtxt(fname) value…

In the post above, they do not call: [image] Hirshikesh_Raj: ux.vector.setValueLocal(dof, values_x[x_c]) but ux.vector().vec().setValueLocal(dof, values_x[x_c])

I am able to fix this by using this: for index in sorted_indices: dof = dofs_on_left_side[index] ux.vector()[dof]=values_x[x_c] x_c +=1
