I’m trying to plot a normalized concentration field as a two dimensional contour for a given diffusion time of 1 second. Instead of getting a meaningful plot my output is a blue square.
!
Any help would be greatly appreciated.
What do you mean by “normalized”
Your factor is
In[76]:= nn = 1/(12. 3.14 10^-8)
Out[76]= 2.65393*10^6
with this I get
In[80]:= Exp[-(((x - 5)^2 - 1)/nn)] /. x -> 0
Exp[-(((x - 5)^2 - 1)/nn)] /. x -> 25
Out[80]= 0.999991
Out[81]= 0.99985
Seems your expression is virtually constant, so, no contours
Hello, I rewrote my equation using different Mathematica syntax (Exp[] instead of using E^2) and was able to get contour lines. However, I anticipated a significantly different pattern. By normalized I was just referring to the diffusion in my system as steady state.
you can see my Mathematica input/output as well as the contour plot I should have created below.
Ok. But without detailed information about what you are doing it is not possible to give a reasonable answer.
And: look at the rules. Don’t paste pics, but code.
