I am trying to solve an electrostatic poissons equation with 2 different materials. I am trying to compute the electric potential for a sphere (ϵr= 10) embedded inside a box (ϵr= 1). [image] I am getting the below error at the affineFEoperator step: julia> op = AffineFEOperator(a,b,U,V) ERROR: pr…

[image] balaji_sriram: MethodError: no method matching epsr(::VectorValue{3, Float64}, ::Int8) That’s because your epsr function should now take ∇(u) as the first argument since you are composing it with (∇(u),tags), e.g. function epsr(∇u, tag) if tag == box_tag return epsr_box *…

[image] balaji_sriram: a(u,v) = ∫( (∇(v)).(epsr*(∇(u))) )dΩ This doesn’t look right. The dot product operator is ⋅ ( unicode dot operator , which can be typed with \cdot<TAB> at the julia> prompt or in editors with appropriate plugins), not . (period). A dot product can also be written dot…

Thank you very much. I am relatively new to julia programming. I modified the original code using the dot() operator instead of “.” as you suggested .I am writing the modified section of the new code below. function epsr(tag) if tag == box_tag return epsr_box elseif tag == sphere_t…
