No. I found a mistake in one of my boundary conditions, and started to check how I could compute steady state of a simpler problem using a boundary value solver....

In case you are interested in my code [note! I have successfully solved at least 3 PDEs using MethodsOfLine.jl, so I have a little experience with it]: ```julia # PACKAGES...

Hm... I also tried with the following re-formulation (the model is the simplified Euler equations, i.e., without energy balance): This model avoids division by some variables, at least in the...

> Can you write that as `Dx(m(t,x)^2/p(t,x))`? Yes, I tried that prior to writing `Dx((m(t,x))^2/p(t,x))`. I have tried to avoid registered functions in BCs... Here is the latest attempt: ```julia...

Bugs is a part of life; let me know if you figure it out. In the mean time, I'm racing on with trying to learn the intricacies of ModelingToolkit.

I'm not *explicitly* using `structural_simplify` in the code that produces the error. Is `structural_simplify` used *implicitly* in the `linearize` function?

Hm. OK. In case `#2727`, the error seems to be related to equating two `parameters`. I have no statements equating parameters. However, I do "reuse" parameters in different components: I...
