Assembly vector of solution

NGSolve

Hi guys,
I have a question.
How is assembly the vector of solution about the elements and the degree of freedom (DOF)?
Ex:
gfu.vec.data = a.mat.Inverse(freedofs=fes.FreeDofs()) * f.vec

gfu.vec= element 1 - dof 1
element 2 - dof 1
…
element n - dof 1
…
element 1 - dof m
element 2 - dof m
…
element n - dof m
whit n and m the number of element and the number dof, respectively.

Hi andressa,

checkout the dofs section of the documentation “Exploring the mesh topology” here to see how you can get the dofs of each element.

Best wishes,
