16.3.4 Importing a Flamelet

To import an existing flamelet file

1.   Select the Import Flamelet option in the Chemistry tab of the Species Model dialog box.

2.   (steady flamelet only) Select either Standard, Oppdif or CFX-RIF format under File Type.

3.   (steady flamelet only) If you selected Oppdif as the File Type, choose a Mixture Fraction Method. Select Drake if you want to calculate the mixture fraction using carbon and hydrogen elements. Select Bilger to calculate the mixture fraction using hydrocarbon formula. Select Nitrogen to calculate the mixture fraction in terms of nitrogen species.

4.   (steady flamelet only) If you selected the Oppdif Flamelet Type, you have a choice of importing Single or Multiple OPPDIF files.

5.   Click the Import Flamelet File... button. In the resulting Select File dialog box (see Section  2.1.6), select the file (for a single flamelet) or files (for multiple flamelets) to be read in to ANSYS FLUENT.

After you have completed this step, you can skip ahead to the Table tab of the Species Model dialog box (see Section  16.7).
