python - PDE solver that handles constraints -


i trying solve system of partial differential equations of general form

f(f(x,y), f'(x,y), f''(x,y), g(x,y), g'(x,y), g''(x,y)) = 0

where derivatives may taken respect both x , y , f(x,y) , g(x,y) subject constraint

g(f(x,y),g(x,y)) = 0

i wonder if there exists (preferably python based) solver (not method, know methods) can deal problem of kind? appreciate , apologise if question seems general.

such problem require initial conditions , boundary conditions satisfied obtain unique solution. need provide domain (geometry) solver. think must @ finite element solvers in python.

just quick google search provided few finite element solvers in python, have not tested any. guess starting point.

sequelize.js - Sequelize: sort by enum cases -

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
