Hi,
I have a quick question for something that I, for some reason, have not been able to find. Is there documentation available that will provide me with all of the available functions that I can use in expressions and in postprocessing?
For example, I used MATLAB to perform an AC sweep of a model I created, and one of the values of interest was the amplitude of a resonating beam. Now, I am able to access these values, for example, in the x-direction with u_amp_smpn.
However, I want to create a Bode plot of sorts, and plot the frequency response on a dB scale. Thus, I need to normalize my data by dividing u_amp_smpn by the maximum value stored in u_amp_smpn. However, I have not been able to determine if there is in fact a max() function. I have tried using max(u_amp_smpn), however I'm told that max() takes at least two parameters. Could anyone provide me with a resource that lists these sorts of details?
Thanks!

Hi,
there is a list of the functions in 'Documentation'-->'COMSOL Multiphysics'-->'Reference guide'

Hallo,
Use COMSOL with Matlab.
The command "lookfor bode" in Matlab command line will give you the functions you are interested in, I think.

Actually (in 5 anyway) it's called the Reference Manual. On page 213 begins a section called Operators, Functions, and Constants. I agree this is hard to find. I don't know how many hours of my life have been wasted looking for this again, after I've forgotten where they hide it. Pity there isn't a function help browser like in Matlab or Mathematica.
