When computing hydrostatic pressure, the test space is different from the trial space but (if the boundary conditions are correctly set) then the system is still solvable.

## Reason
As we test more problems, we want to enhance the mortar contact machinery to extend the benefits of mortar to new simulation scenarios.
## Design
To be discussed in PRs.

Dear Dr.Lu:
Recently, I'm having a problem with PINNs simulation and would like to ask for your advice. The problem is described as follows:
**PDE:u_xx+u_x=u_t**
**BC1:u(0,t)=0**
**BC2:u…

Goal is to have a working LQG (LQR + Kalman filter) for the cylinder wake as a baseline controller. So far I've gotten the following to work (see `examples/cylinder/control` and `examples/cylinder/no…

Multilinear operators (tensors) appear in quadratic systems. If a linear system is
```
x' = A x + B u,
y = C x,
```
a quadratic system would be
```
x' = A x + H^(1) (x kron x) + B u,
y = C x.
```

We've had a number of discussions over the years on how to improve the accuracy of the solutions ASPECT computes. Some of these have been implemented, for example @ian-r-rose's implementation of the c…

## 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…
