Hi every body,
I modeling a transient case which has a time dependent volumetric heat source applied in a wall. I wrote the UDF as follows: #include "udf.h" #define C1 0.0029369048 //define constant term DEFINE_SOURCE(heat_gen,cell,thread,dS,eqn) { real source; real time; time = CURRENT_TIME; //taking time value; source = time*C1; //time dependent heat source; dS[eqn] = 0; return source; } I Interpreted it with no problem, but when i hooked it to a wall it made this error: heat_gen: wrong return type: void udf function expected Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. So any help??!! |
