dear all:
i come across a udf problem. the case ran well without the udfs. but when the udfs were compiled, built and loaded, the error signal would appear and the interation would not process a bit. here is the error signal: 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. Error Object: () the udfs are compiled and loaded successfully as: xforce.c yforce.c zforce.c uds.c Generating Code... # Generating udf_names.c because of makefile xforce.obj yforce.obj zforce.obj uds.obj udf_names.c # Linking libudf.dll because of makefile user_nt.udf udf_names.obj xforce.obj yforce.obj zforce.obj uds.obj Microsoft (R) Incremental Linker Version 6.00.8168 Copyright (C) Microsoft Corp 1992-1998.
