linux下fluent并行编译udf出错

maye761

我仔细看了一下编译，发现单核编译可以成功，但多核并行编译就不能成功。错误提示为：
The UDF library you are trying to load (libudf/inamd64/3d_host/libudf.so) is not compiled for parallel use on the current platform (lnamd64)

no error
/cae/maye/fluent/test/libudf/lnamd64/3d_host/libudf.so
既然单核能编译说明编译环境没有问题，但为什么并行情况下按了build还没出错（比单核情况下build会多几行重复的），但按了load就出现上面的错误，单核和多核在windows我用的是同一个udf，没有修改过（见附件），请问这是什么原因？是否需要修改一下udf在并行环境下？

udf文件是：

#include <stdio.h>
#include "udf.h"

DEFINE_CG_MOTION(wall, dt, vel, omega, time, dtime)
{
        if(time<=8.0)
                {
                        vel[2]=-0.75*time;
        }
        if(time>8.0&&time<=14.0)
                {
                        vel[2]=-6.0;
        }
        if(time>14.0&&time<=22.0)
                {
                        vel[2]=-6.0+0.75*(time-14.0);
        }
                if(time>22.0)
                {
                        vel[2]=0.0;
        }
        Message("\nUDF value: velx=%f",vel[2]);


}

build可以通过，但不能load，一load就出现以下错误，改了udf变成并行也没办法。

多机器并行还是单机多核并行？

你这个UDF在我的linux 机器上并行编译、load都没有问题，我的机器是单机多核。
