Errors when trying to latexify the model equations

[Sven-Mattus]

Hi,

I'm currently using pybamm 24.11.0. When I try to use the latexify function for the model equations (mainly interested in the DFN), then I get several different errors, depending on what I try to do and which submodels I use.

E.g. generating the equations for simple base models like SPM() or DFN() including a .png file works fine. However,

1. Using ageing sub models, I can generate the equations and display them (e.g. using display()), but when I try to create a .png or .pdf with model.latexify("dfn_test.pdf"), I get the following error:

Exception has occurred: RuntimeError
'latex' exited abnormally with the following output:
b"This is pdfTeX, Version 3.141592653-2.6-1.40.26 (MiKTeX 24.4) (preloaded format=latex.fmt)\r\n restricted...

Are there any specific latex programmes/versions we have to install to make this work?

2. When I use the particle mechanics (swelling only) model, then I get the following error:

/pybamm/latexify_pybamm.py

3. I also got the following error regarding the geometry or some variable limit:

   ~~~^^^^^^^^^^^^
   KeyError: 'min'

Should this work or are those known issues/instabilities?

What are the conditions (like versions, submodels, settings of geometry and parameters etc.) and recommendations to make latexify work reliably?
This would be quite helpful to analyse the models and equations used as well as for generation presentations/reports etc.

thank you and best wishes,
