FLUENT received fatal signal (ACCESS_VIOLATION)???
Dear Friends,
I wrote a DEFINE_ON_DEMAND type code to read some data from files into FLUENT so that I can use the data in later source term calculations. After interpreting it successfully, I clicked "EXCUTE" the Excute on Demand panel and I got this error message: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save cas/data under new name. 3. Exit programme and restart to continue. 4. Report error to your distributor. Error object:() I have no idea what the problem could be, I am seeking some experts' opinions......... Here is that part of the code(The matrix definitions was defined as global variables and were not pasted here): DEFINE_ON_DEMAND(read_rho_exeyez) { int numnodes; int i; FILE *ifp; // Pointer for the data file FILE *kfp; int k=0; numnodes = xdirnodes * ydirnodes * zdirnodes; // Calculate total number of nodes in volume ifp = fopen("Rho.dat", "r"); // Open data file for scanning kfp = fopen("ExEyEz.dat", "r"); //*** READ IN VALUES ***// for(i=1; i<=numnodes; i++) { fscanf(ifp, "%f", rho[k]); fscanf(kfp, "%f", dvdx[k]); fscanf(kfp, "%f", dvdy[k]); fscanf(kfp, "%f", dvdz[k]); k++; } fclose(ifp); fclose(kfp); } |
Pointers... always a problem
You should put a check for the pointers:
Code:
if (NULL == if) Code:
fscanf(ifp, "%f", &rho[k]); Dragos |
