I'm not sure which volume integrals you refer to but if you're
thinking about how FEniCS assembles variational forms, it's all
described in great detail in this book:

Hi Andres,

I want to know how is the area in Fenics calculated?

Thanks for you help.

Hi,

I wanted to calculate the strain energy and I wanted to know how that is derived inFenics and that is the area.

I still don't understand. Area of what?

I think you need to look at the link I sent. It is all explained in
the book.

luckas, chapter 8 of the fenics book talks about quadrature, which is probably what you are looking for.

When will the book be available in print ?

I want to know what is expected in the volume integral Fenics.

Thanks for you help.

As soon as possible. We are still waiting for some authors to fix some
minor issues.

You really need to come with more details for us to be able to help you. There
are quite a few aspects regarding a volume integral in FEniCS, which you can
read about in the book Anders already has pointed to.

Hi Andres,

I wanted to know what is expected in the volume integral Fenics or to explain exactly with energy3 = inner(0.5 * (grad (u3) + grad (u3). T), sigma (u3)) * dx
E3 = assemble (energy3, mesh = mesh), this command will assemble the volume udexpected here, I want to know exactly what makes the assemble command.

A lot of things will happen when you call the assemble command, too
long to explain here. Please read the FEniCS book where it is
explained in great detail.
