The new syntax seems to be Probably the error could be more informative? Or during the construction of |
I see, I missed the new synthax, thanks a lot ! |

Is there also a new way to call "remake" function ? newprob = remake(prob, p=[D=>0.2])
@time "PDE Solve" newsol = solve(newprob, Tsit5(), saveat=0.1)throw the warnings: ┌ Warning: Initialization system is overdetermined. 1 equations for 0 unknowns. Initialization will default to using least squares. To suppress this warning pass warn_initialize_determined = false. To make this warning into an error, pass fully_determined = true

Did you reverse the order of x and t everywhere in the problem setup? I have multiple parameters in my problem that might be the source of the continuing issue. Thanks. MethodError: no method matching namemap(::Type{ModelingToolkit.VariableType})
The function `namemap` exists, but no method is defined for this combination of argument types.
Closest candidates are:
namemap(::Type{ModelingToolkit.VariableType}) (method too new to be called from this world context.)
@ ModelingToolkit Enums.jl:215
namemap(!Matched::Type{LinearSolve.OperatorCondition.T}) (method too new to be called from this world context.)
@ LinearSolve ~/.julia/packages/EnumX/Aoxb1/src/EnumX.jl:130

it seems again that the syntax has changed Parameters Tutorial but I couldn't make it work. the new error is
|
That's a completely different thing. Using the SciMLStructures interface for quickly replacing tunables is an interface for optimizers. It's separate from @cartiery what's your full example? |
Describe the example
I was doing PDE discretization using MOL (julia v1.10.5). I did the upgrade to julia v1.11.1, going along with packages updates, and now I've some error.
Minimal Reproducible Example 👇
Error & Stacktrace⚠️
Working Environment (please complete the following information):
using Pkg; Pkg.status()using Pkg; Pkg.status(; mode = PKGMODE_MANIFEST)versioninfo()Additional context
Packages version where MWE works:
The whole story is that I uninstalled julia that I had manually installed, to install it through MS store (to have juliaup). Juliaup installed last julia release, so I went from v1.10.5 to v1.11.1. I tried to install packages through julia v1.10.5 channel, but it installs same packages version as in v1.11.1 channel (which do not work), so I'm stuck with this MOL error.
