Issue with NODE_POS_NEED_UPDATE (v)
 

Hi Everybody

In the following simple code, the program does not go through the "if" ( nothing is being written in the file) which is quite surprising for me since the same piece of code works well when I use that in a deforming mesh function. It seems NODE_POS_UPDATED(v); does not work correctly.

Thanks for sharing your ideas. Parsa

------------------------------------ #include "udf.h"

DEFINE_EXECUTE_AT_END(sort) {

Domain *ddx=Get_Domain(1); Thread *tf=Lookup_Thread(ddx,10); face_t f; Node *v;

int n;

FILE *fp;

fp=fopen("checkdata.dat","a");

begin_f_loop(f,tf) { f_node_loop(f,tf,n) { v = F_NODE(f,tf,n);

if (NODE_POS_NEED_UPDATE(v))

{

NODE_POS_UPDATED(v);

fprintf(fp,"%12.4e \n",NODE_X(v));

}

} } end_f_loop(f,tf);

fclose(fp);

}
