How to make zip work with more than 6 elements?

Coming from Python and Julia in my area of simulation, the expressions come from SymPy and can often involve many variables. I find the limitation on the number of produces...

UndefVarError of an irreducible variable

I forgot to mention the version information: ```julia Julia Version 1.9.1 Commit 147bdf428cd (2023-06-07 08:27 UTC) Platform Info: OS: Linux (x86_64-linux-gnu) CPU: 64 × AMD Ryzen Threadripper PRO 5975WX 32-Cores...

UndefVarError of an irreducible variable

I was browsing other open issues and realized that this may be the same issue as https://github.com/SciML/ModelingToolkit.jl/issues/2173.

UndefVarError of an irreducible variable

Just a quick update on this issue. MTK 8.60.0 can properly build the `ODEProblem` with ``` prob = ODEProblem(sys, ModelingToolkit.missing_variable_defaults(sys), (0.0, 1.0)); ``` But solving the problem yields `InitialFailure`. Thanks...

UndefVarError of an irreducible variable

A tangential question is related to the irreducibility of `v` of `Diode`. Since `diode.v ~ p.v - n.v`, does MTK automatically mark `p.v` and `n.v` as irreducible? If not, could...

Tx line in DP formulation

@aaliqureshi I'm separating the DPLine model from Line so that I don't have to switch between branches. The DPLine model does not consider transformers (tap/phi) for now. Can that be...

Testing a package that depend on CondaPkg.jl creates a new environment every time

My workaround is to edit `runtests.jl`. At the very beginning, insert ``` if gethostname() == "MY_DEV_MACHINE_NAME" ENV["JULIA_CONDAPKG_ENV"] = "/PATH/TO/MY/DEV/MAMBA/ENV" ENV["JULIA_CONDAPKG_OFFLINE"] = true end ``` I guess a better solution is...

Testing a package that depend on CondaPkg.jl creates a new environment every time

For an unknown reason, the environmental variables are not respected in the very first test after updating deps. This is the full output. Not sure if that's accidental. I can...

Testing a package that depend on CondaPkg.jl creates a new environment every time

No problem! Thanks for your reply! I ran the same test that contains the following at the top of `runtests.jl` ```julia if gethostname() == "ampere" ENV["JULIA_CONDAPKG_ENV"] = "/home/hacui/mambaforge/envs/a" ENV["JULIA_CONDAPKG_OFFLINE"] =...

Using with CUDA Solver?

> ```julia > A = sprand(Float32, 1000, 1000, 10 / 1000) + 100I > ``` Hello @haampie , If the matrix is ill-conditioned, say `A = sprand(Float32, 1000, 1000, 10...
