Boundary conditions about amr-wind HOT 3 CLOSED

Hi, you can add your own user defined function (UDF) here: https://github.com/Exawind/amr-wind/tree/main/amr-wind/physics/udfs

use linear and power law as examples but note that they don't use time which is the 4th input

amrex::ParallelFor(bx, [=] AMREX_GPU_DEVICE(int i, int j, int k) {         
   for (int n = 0; n < ncomp; ++n) {                
      dop({i, j, k}, marr, geomData, time, {}, n);        
    } });   }}

@gantech can you provide an input file snippet for udf's? I don't see one in the reg tests

Thanks, its works. I think that to add it in examples or/and documentation good idea.
