4.14.16 RadTherm Files

The option to export a RadTherm file type is available only when the Energy Equation is enabled in the Energy dialog box. Select RadTherm from the File Type drop-down list and select the surface(s) for which you want to write data in the Surfaces list. If no surfaces are selected, the entire domain is exported.

Select the method of writing the heat transfer coefficient ( Heat Transfer Coefficient), which can be Flux Based or, if a turbulence model is enabled, Wall Function based.

Click the Write... button to save the file, using the Select File dialog box. A PATRAN neutral file (e.g., file.neu) is written containing element velocity components (i.e., the element that is just touching the wall), heat transfer coefficients, and temperatures of the wall for any selected wall surface. If the wall is one-sided, the data is written for one side of the wall. If the wall is two-sided (a wall-wall shadow pair), the values are written only for the original wall face, not for the shadow face (which is a duplicate).

You have the option of exporting data at specified intervals during a transient calculation through the Automatic Export dialog box. See Section  4.16 for the complete details.
