Interpolating 3-D data

Hi all
I am trying to use some 3-D data i.e. temperature profile across and x and y surface. The data is stored in and excel file.
I want to interpolate the data to form a function as T = f(x,y) and then use that function in the model.
I have seen COMSOL can easily interpolate 2-D data, but not sure how to deal with this 3-D data.
Any suggestions on how to do this in COMSOL ?

I think you need the z coordinate's data. Because the geometry is 3D, the independents are x, y, z basically in COMSOL Multiphysics. I mean the data has 4 arguments - x, y, z, f(x,y,z).

Hi Tae
the geometry is actually 2-D i.e. x and y
and the dependent variable is Temperature
so I want to plot Temp = f(x,y) and interpolate it as a function.

Hi,
you can use an interpolation function. In order to get a 2D interpolation with two independent variables you have to choose file as data source and enter 2 into 'number of arguments'. The COMSOL help provides you with the details.
