hi..

i'm newbies in labview..just want to ask a few questions. i have 4 differential equations (non-linear), and it is a mass balance eqn. of activated sludge process. my question is how to design the block diagram(diff eqn) and then connect all together to get one output?

Hi,

You can use formula node to write equations.

Another approach is to reformulate your differential equations as difference equations.  Then you can loop through the arrays and perform relatively simple calculations on each element.
