Hi,

I have two questions:
1. an analytic cunction that has one argument - sigmaxx that I want to incorperate in another analytic function that has another argument = ec.normE. I cant do it no matter what I try. Please help me. I am using comsol 4.2a

2. I am trying to incorporate an interpolation function inside an analytiv function. Again with ni succuss.

Can someone explain to me why and how to silve the problem

ave_m=(b_thresh+((b_thresh-d_thresh)*flc2hs(sigmaxx-0.7,0.35)+700))/2
diff_m(-b_thresh+((b_thresh-d_thresh)*flc2hs(sigmaxx-0.7,0.35)+700))/2

arguments-sigmaxx

an1=(flc2hs(ec.normE-ave_m(sigmaxx[1/(s/m)]),diff_m(sigmaxx[1/(s/m)])))
arguments: ec.normE, sigmaxx

error:
Wrong number of function arguments.

thanks
Shirley

This is easy:
1. First create an 'Interpolation' function, default name int1, by choosing 'Table' and enter in the column for [t,f(t)] values : [1,1], [2,4], [3,9], [4,16]
2. Create a new analytic function 'an1', in the expression put 'int1(x)' and in plot parameters choose 'min=1' , 'max=4'
3. Press 'Plot' button on top left and you'll see your analytic function created from the interpolation function

No, this is not possible.
