how to solve a one dimension thermal diffusion equation
 

hi

i am new to these forums and new to labview.

please see if you can help me with this -

i am taking 8 sets of data - over 2 minutes (120 data points - sampled at one second apart. The 8 data points are along 8 equidistant points on a rod and the data itself is the temparature, recorded as a voltage (v) by 8 thermistors

The data satisfies the following equation -

d^2v/dx^2 = k d^2v/dt^2

that is the one dimensional laplacian of the voltage = k times the 2nd time derivative of the voltage

how to solve the equation in labview !!??

I am hoping that you have come to realize that THIS forum (ChiefDelphi) is focused on the various FIRST robotics competitions, and is not a general LabView support forum.

LabView does have its own forums, just perfect for the kind of question you have asked. Perhaps you may be more successful there.

(For what it is worth, I failed thermodynamics in college. But I do know that the heat can be modeled as voltages in a resistor network, and that doing calculus in LabView is possible using the various "Calculus VIs". All I had back then was a 4-function calculator...)
