Hello,

Does anyone know if a finite element skeleton source code exists. Finite element can be used for structural memebers, gas dynamics, etc. But the over all stepping software is the same and then just input the core equations.

My application is for pseudo one dimensional compressible converging diverging nozzels. So I would have energy, momentum and continuity. I would then itterate the shape factor A(x) until I got the desired mach numbers at various locations along the path. In theory I would like to be able to model 2 converging diverging nozzels in series.

I am guessing the skeleton code exists so I would hate to spend huge amounts of time re-inventing the wheel.

Thank you,

Awesome, thank you.

I will let you know how it works.
