Hello all.

I am modeling the flow of acid through a porous sample. Currently, I am trying to generate a random initial porosity distribution in the sample. The porosity changes with time, therefore I have used a DEFINE_PROFILE UDF to define the porosity. Between iterations, the porosity is stored in UDM. I want to initialize this UDM by defining the its value at some specified coordinates and have Fluent interpolate between these points to generate a continuous profile.

I have successfully read the profile from a text file but I cannot seem to figure out how to apply it to the UDM and interpolate. Does anyone know how I can do this? Below I've attached a simplified version of the profile I am using.

((udm-prof point 4)
(x    -1.73E-02    -2.83E-03    -1.00E-02    6.41E-03)
(y    1.42E-02    6.94E-02    1.98E-02    8.50E-03)
(z    4.21E-03    -1.76E-02    6.85E-03    9.16E-04)
(udm-0    0.2    0.3    0.4    0.1))

Any help would be greatly appreciated.

I am still struggling to figure out how to do this. Any help would be greatly appreciated.

Are you asking for how to hook it in ANSYS?

I think I understand how to hook it. I've followed the instructions here but when I check the values by looking at the contour, they all show a value of 0 for the UDM. I've tried all three of the interpolation methods but get the same result of 0 every time.

in my results i am getting graph showing points...
how to transform or convert them into continuous curve or line
