I am very thankful if anybody give me a suggestion. It is well described who to build 2D Geometry from 3D in COMSOL. Imagine, a cross section of first result (Lets call the first results as S(x, y, z)) should be imported in the second "Component" as a position dependent variable. e.g. S(x, y=constant, z). Final aim it to solve "2D Component" for different cross sections using "parametric sweep". It is easy to make a cut plan and plot 2D cross section but I could not figure this out how to access to 3D data to use in 2D model. Using data export as a text file and then importing the data is not interested.
Hi Vahid
Linear extrusion is a way to achieve that.

Something important is that using this method you'll never define a variable, instead you just make a coupling between a 3D boundary and a 2D domain.
Hi, Thank you very much for your nice suggestion. Unfortunately comparison between plot of cut plan and value that is achieved from" Linear extrusion" shows they are different. This means the data does not peaks in the right way. The "extrapolation tolerance" also seems to has no influence. I am confused :-( . I will appreciate for more help.
Hi
I think the identity mapping coupling doesn't have that disadvantage, but you have to be careful of placing your 2D face in the exact same coordinates that the 3D boundary.
Salute To Juan, Special Thank to you. Problem solved with adding extra points to 3D Geometry in order to define exact points in both 3D and 2D.
Wish you success in your life and research.
