Hi,
I want to import one csv file having radius versus refractive index data. And i want to use this data for refractive index in my structure that is a circle. (please find attched file).
Approach:-
I am using interpolation function to select this file and use the option "space coordinates as the arguement". In Electromagnetic waves, I use addition wave equation in which I choose the circle as a domain & Refractive index in electric displacement field. And I make refractive index to be user defined. Where I Chosse mod1.int1 as the function.
after running I get the error:-
wrong number of function arguments.
- Name: mod1.int1
- Number of arguments expected: 1
please help.

Hi
if you are in 2D your space coordinates are x,y and not "r". So from what I read, you should import your file into an ordinary interpolation function with the argument "r", then define a cylindrical coordinate systems i.e. sys2 in your domain and call your interp1(sys2.r) with this "r" value

Good luck

Hi,
thanks a lo for reply. Can you please tell me how to define sys2.In definition I found boundary system 1, which I duplicate for boundary system2. In boundary system setting window, there is "coordinate name" option. What should I put there. What if I want to use polar coordinate. Is there any option that I can use for inserting special symbol like theta, phi. Can you please do the changes in attached file and then attach it. Thanks a lot.
Regards
Deepak

Hi
under Definitions (right click) you have Coordinate Systems and therein you can define different types: cylindrical, spherical ...
the reference to the coordinate system is sys2.r, sys3.r etc where "sys1" is the default predefined boundary coordinate system, and "sys2" is the first user defined coordinate system, sys3 the 2nd etc
then you "." add the variable names, usually r,phi,a for a cylindrical system etc
