hello,

I am doing a simulation which the pressure in the top boundary is nonuniform, It varies with x direction and I calculated it use another software, it generate a file which consist the pressure value with different x direction values. the time is keep constant, the pressure just vary along x direction. Now I want to use this file as the boundary condition for another part. and try to use nonuniform List<Scalar>, but it has some errors, I do not why? can this method solve my problem? or I should consider another boundary conditions?

the error is wrong token type - expected Scalar, found on line 109 the punctuation token ')'

In the list you declared the number of values to 78 but there are 71 numbers, they should be the same.

I find this mistake, and when I increase the same number, it woks, but it still have some mistakes. and I want to consult you just now in the last questions you helped me,it will be more specific, and now I need to do interpolation of these discrete values, then use this as boundary conditions for another boundary, Do you have some methods about this?

swak4Foam is a great utility that can be used to generate boundary conditions.
