I want to import set of data of density variable for topology optimization. i am able to import the data of density variable using interpolation function. I want to multiply this data with material property of each element.

Is it important that it is constant per element?

If not, you can just use the interpolation function as is in the input field for density, and there will be a corresponding variation over the element.

If you want an element constant value, I assume that you want the value of the interpolation function at the centroid. Then you can write an expression like centroid(int1(X,Y)) as input.
