Dear Daniel,
yes, I defined a class derived from deal::Function and it seems to work for
me.
Basically, my motivation to call VectorTools::interpolate is to compute the
nodal values (scalar field --> DOFs) in the triangulation based on the
formula implemented in the just derived class.
During th
Hello,
This error often happens when you don't have enough memory to compile the
program. Try using only one or two cores.

Simon,
It looks like all the errors are related to the Sundials dependency
(release 6.0.0). Looking at https://github.com/dealii/dealii/pull/13918, it
seems that you need the latest deal.II release (9.4.0) to support that
Sundials version.
If you don't anticipate needing it I would just turn the d

Simon,
if you get all information you need using VectorTools::interpolate then
this sounds good.
Note that there also is FEFieldFunction(
https://www.dealii.org/current/doxygen/deal.II/classFunctions_1_1FEFieldFunction.html
)
that implements the interpolation for you.
Best,

Hi Simon,
Daniel is right — only Sundials versions 5 through 5.8 are compatible with
deal.II 9.3.2, while Sundials 6 is compatible with 9.3.4 onwards. This is in
fact what is stated in the Spack package, so I don’t quite know how it is that
you’re able to get this mixed configuration:

What is the approach to achieve this?
My only idea is to create a new FEValues object for each quadrature point and
pass an appropriate Quadrature object. But seems to be very inefficient.
This is basically what the VectorTools::point_value() and
