How to use integrals over an axis and explicit dependence on coordinates in a field?

[Divyoj-Singh]

Hi!
First of all thanks for this great package!
I am trying to solve a pde in 3D which has terms like:

and a(x+lcoz,y+sinz, z+ \pi,t)

I tried the integrate function for the field but it calculates the integral for the whole lattice.
I couldn't understand how to write the second term..
Can you please help me with this?

Thanks!!

The partial integral over an axis is typically called a projection and is supported by the project method. I hope this helps!

Yes, that worked, thanks!
