vector valued ConstantFunction with different values in each component

[Lei Qiao]

Dear all,

Now the ConstantFunction in deal.ii can return vector function value but all the components of returned vector are in the same value.
Is there any class can return a vector value with different values in each component?

Or I have to create such a class by myself?

Best,
Lei

I don't think there is a class that can have completely different values in
the various components. But there are functions that allow you to specify a
value (or a function) for one component and set all of the others to zero.

 I believe there is really no such a class when you say no.

I will try to create it.

hahaha. :) Both are correct to me.
