Some nonlinear problems can be very efficiently solved with non-standard methods, possibly abusing the specific structure of the problem. To allow users to efficiently utilize such methods in tandem w…

## Bug Description
If a PDE does not have a time derivative (say the mass equation for incompressible Navier-Stokes), then you will end up solving, for that sub-vector of dofs, the equation: residual…

Hi,
I am trying to write something similar to a **leap-frog** scheme in FiPy. I am trying to understand two things:
#### 1. I want to implement the curl of another vector field as a source term.…

When one changes `uex = sin(2*y)*(1-z**2)` to `uex = sin(2.05*y)*(1-z**2)` in the manufactured solution, the error for the x-component of the flow velocity increases from 3.9229e-14 to 2.672e0.
Wou…

## Reason
Multi phase flow is very important physics for some applications and users including @joe61vette
## Design
One possible design is adding additional terms to the Rhie-Chow interpolation…

I'm facing a problem with the result obtained from the DeepXDE library compared with the literature. It may be probably a mistake of mine, but I think it may be also helpful a discussion for everyone …

I've been encountering an odd bug in my code I'm having trouble identifying. On exit of a successful execution I get met by "malloc_consolidated(): invalid chunk size, aborted (core dumped)". Valgrind…
