specifying varing coefficient - interpolation function

Hi all,

I would like to specify varing htc via interpolation function and apply it to a heat flux boundary condition. I am attaching a sample file.

- Model: 2D-axisymetric (i.e.cylinder, mm), heat transfer in solids, and s-s case
- Features: a heat flux boundary condition with heat transfer coefficient varing along line (not as constant). assigned via interpolation function
- Error: Wrong number of function arguments, Number of arguments expected: 1'

I built a simple 2D axisymetric, heat transfer in solids, and s-s case and added a heat flux boundary condition with heat transfer coefficient which is varing along line. An external htc data set was imported using interpolation function under Global Parameters.

t f(t)
1 50
2 52
3 54
.. ..
399 52
400 50

1) I can see a plot without assiging units, but with units (argument: mm, function: W/(m^2*K)) a horizontal line is only appeared. What should I consider?

2) I am facing the same error message 'wrong number of function arguments' when running the simulation. I believe the number is ok but it repeatedly says it.

Any advice and help will be appreciated,
