hi, all, what's mean enum in UDF sample application, the low is the sample in postprocessing using user_defined scalars.

/***********************************************/

/* UDF for computing the magnitude of the gradient of T^4 */

/**********************************************/

#include "udf.h"

/* Define which user-defined scalars to use. */

enum

{

T4,

MAG_GRAD_T4,

N_REQUIRED_UDS

};

.

.

.

the low of the application is ommitted.

would you have free time, please tell me, thanks in advance

I think enum is the number of user defined scalars.
