is the application installed with the documentation ?
why in mor/toolbox-mor?
I would suggest

• toolboxes/generators/cases/thermal-fin -> geometry + cfg/json
  no ?

also the generated geo file should contain

/cc @thomas-saigre @romainhild

[thomas-saigre]

@prudhomm I documented in https://github.com/feelpp/feelpp/blob/saigre/fix-thermal-fin/mor/toolbox-mor/thermal-fin/case_generator.adoc
I can move those files in the drectory toolboxes/generators/cases/thermal-fin if it make more sense than where it is now. I think I put it in mor becausethe case was build for this toolbox, but we can indeed use is with another toolbox

[prudhomm]

you generate the json file as well ?

[prudhomm]

we could be indeed interested in different physics, eg solid and fluid mechanics

[thomas-saigre]

you generate the json file as well ?

Yes the json is part of the templates

[prudhomm]

the application could generate the json for different physics, in case of fluid mechanics the fin needs to be in a box

[prudhomm]

feelpp_case_generator should be renamed feelpp_case_generator_thermal_fin
