Hello everyone,
I am struggling with the discrete ordinate model in TUI. After succesfully loading a case and turning On the discrete ordinate model with 2 bands, I fail at defining a material refrative index. Here is the relevant part: Code:
/define/materials/change-create/glass/ glass glass is a solid change Density? [no] no change Cp (Specific Heat)? [no] no change Thermal Conductivity? [no] no change Absorption Coefficient? [no] yes Absorption Coefficient methods: (constant piecewise-linear piecewise-polynomial polynomial gray-band user-defined-gray-band user-defined) new method [constant] gray-band band1 (1/m) [0] 0.1 band2 (1/m) [0] 0.8 change Scattering Coefficient? [no] yes Scattering Coefficient methods: (constant piecewise-linear piecewise-polynomial polynomial gray-band user-defined-gray-band user-defined) new method [constant] gray-band band1 (1/m) [0] 0. band2 (1/m) [0] 0. change Scattering Phase Function? [no] no change Refractive Index? [no] yes Refractive Index methods: (constant refractive-band) new method [constant] refractive-band no data required. I am using Ansys Fluent 17.1 in 3D. Thanks in advance, Tony |

Try list-properties for glass and see what it shows for refractive-index.

Thank you for your interest in the question vinerm.

Code:
property name units method value(s) ----------------------------------- ---------- ---------- --------------- ... Absorption Coefficient 1/m constant 0 Scattering Coefficient 1/m constant 0 Scattering Phase Function isotropic #f Refractive Index constant 1 And after the command, it is changed to Code:
property name units method value(s) ----------------------------------- ---------- ---------- --------------- ... Absorption Coefficient 1/m gray-band (0.1 0.8) Scattering Coefficient 1/m gray-band (0 0) Scattering Phase Function isotropic #f Refractive Index refractive-band #f |

Could be a bug in that version. It is showing unassigned (#f). One way out is to write a user-define material database after defining the coefficients for the bands using GUI. The user-defined database is written in Scheme language and you can open it in any text editor. Look for the values that you have defined. Now, anytime you want to change the values, delete the existing material, change the values in the Scheme file, and reload the Scheme File via User-Defined Database. You won't have to modify any of the properties using the commands that you are using. Modify all together within the Scheme file and just read it.
