This might be a question better suited for the Software Recommendations side of S.E., however I do believe that people who frequent this part of S.E. are more likely to be able to answer this question.
I am looking for a free (not only as in freedom) alternative to Comsol Multiphysics. Here is the tricky bit: I am not simply looking for a modelling and simulation package, of which there are loads, rather I am looking for a free solution that has as similar syntax to Comsol as possible. Maybe there is some package you can run together with Octave? If so, I haven't found it. Any help will be greatly appreciated!
[Edit] I would need the software for numerical modelling and simulation. Fluids flowing between various containers, heat conduction, ect. Simulating solutions to various PDE's in short. The main functionality I am looking for the other software to parrot is Comsols Model Wizard.
