Help for Fluent udf on parallel computing

KAILI

Hello,

My udf is used for dynamic mesh.

In paralle,the error:

Updating mesh at time level N... done. time=0.000000 omega=1000.000036

This is the udf:

#include "udf.h" #include "unsteady.h" #include "stdio.h" #include "stdlib.h" /************************************************** **********/

real current_time = 0.0 ; /************************************************** **********/

DEFINE_CG_MOTION(Pitching,dt,vel,omega,time,dtime)

{

#if !RP_HOST

current_time = CURRENT_TIME ;

vel[0] = 0.0 ;

vel[1] = 0.0 ;

vel[2] = 0.0 ;

omega[0] = 0.0 ;

omega[1] = 0.0 ;

omega[2] = 17.453292222 ;

Message("time=%f omega=%f\n",current_time,omega[2]*180.0/3.1415926) ;

#endif /* !RP_HOST */

}

The code worked well in the serial process.

Do you know what happens?

Thanks!
