How to import a complicated wire geometry into CADFEKO?

Hello

I want to plot an analytical curve which has integrals in its parametric equations. I couldn't find the integral function in CADFEKO. I have generated this analytical curve in MATLAB and I want to import it to CADFEKO, is that possible? 

suppose the analytical function for the curve is given as

phi(l)=integration(0 to l, alpha(l))  where alpha(l) is a complicated function where the integral cannot be evaluated analytically.

x,y, and z= are function of alpha(l)

any suggestion will be much appreciated.

    Since no one has answered my question, I would like to answer it by myself. 

    fist of all, the wire geometry should be programmed in MATLAB software. then,  the x,y,z components should be saved in a matrix as

    A=[x; y; z] where x, y, z are row vectors. then the function dlmwrite() is used. see the attached pictures.

     

    in Feko software, we should import the text file (check the attached image).

    downsimple function is used to reduce the number of point data in x,y, z components (number of data/10). my data was 1000 which is a huge data that makes feko slow, as consequence,  i have reduced the data point to 1000/10=100 points which convenient for feko.

    if anything is not clear, you are free to ask me.

    i m here to help
