Problem with creating vector with scalar function components

[dokken]

@avishmj

However, when I am printing the vector V, it gives me [0, 0, f_20] . What does f_20 mean?

It is the unique name dolfin has given to your function u. You can change this by:
u.rename("replace_with_new_name", "")

@avishmj

S = (mu/2)*(grad(V) + ((grad(V)).T))

Shouldn’t this be either:

• S= (mu/2) * (grad(V) + grad(V).T)
  Or equivalently
• S=mu*sym(grad(V))

For future problems please make a minimal reproducable example, following the guidelines in:

Here are a few tips to help get your question answered: Phrase the title of your post as a question and make it meaningful. Check that your question hasn’t been asked before using the search functionality. Post a “minimum working code example” (MWE) to illustrate the problem: A MWE is the simplest piece of code that reproduces or explains the problem you have. It must be possible to take the MWE, paste it into a file and run it, without any extra modifications. Good MWEs can be as little as …
