Hi,
I faced this problem when trying to run udf in parallel mode, pay attention to the code enclosed between the parallel directives (if RP_NODE......end if), within this code section "try to eliminate instructions that modify common variables values". her is an illustrative example Code:
real k_sqr,kx,ky,kz,amp; #if RP_NODE k_sqr=kx*kx+ky*ky+kz*kz; amp=2; #end if Code:
k_sqr=kx*kx+ky*ky+kz*kz; amp=2; Code:
999999 (../../src/mpsystem.c@1123): mpt_read: failed: errno = 104 999999: mpt_read: error: read failed trying to read 30 bytes: Connection reset by peer The fluent process could not be started. |

Dear All,
This is my serial UDF. After reading the manual I am getting confused with int ex node and stuff. Could anyone please convert this UDF to parallel? It is working properly for serial system. #include "udf.h" DEFINE_PROFILE(pressure_profile,t,i) { real x[ND_ND]; real y; face_t f; begin_f_loop(f,t) { F_CENTROID(x,f,t); y=x[1]; F_PROFILE(f,t,i)=(0.4898-y)*998.2*9.81; } end_f_loop(f,t) } And I will use Cluster which is in Linux system. How can I make the UDF visible to every node?? Thanks a ton in advance. Tanjina |

hey
can anyone could help me to make my udf parallel? DEFINE_PROFILE(porosity_function,t,j){ real x[ND_ND]; cell_t c; begin_c_loop(c,t){ C_CENTROID(x,c,t); if(pow((x[1]-yo[0])/R,2)+pow((x[0]-xo[0])/R1[0],2)<=1 ) F_PROFILE(c,t,j)=0.9; else F_PROFILE(c,t,j)=0.1; } end_c_loop(c,t) } |
