I had compiled a udf file(.dll), when I copy it to work directory and run the case with udf_flag open, the error appeared showed as attachment. who can tell me the reason? Thank you very much.

try it with V2.4

Greetings,

In order to diagnose the issue you are facing, additional information would be required. What udf(s) have you used/enabled (Please list the flags enabled in udf.in and the *.c used/altered to compile the udfs)? Does the case run without udf enabled?

Sincerely,

I have used user_post and user_point(user_post_flag=1 and user_point_flag=1 ; user_post.c and user_points.c are used to compile the udfs), the case can run both without udf enable and with other .dll. the attachment is my user_post.c, and predefined user_points.c is used without modification

Greetings,

When using user_point_flag, ensure user_points_data.c is always being used along with user_points.c to compile the udf. Also ensure that the user_dynamic_routines.c and the *.h headers are obtained from the same version as the solver (2.3.10) for this case.

Could you clarify if the case stops with that error right before the first iteration of the simulation, or in the middle of the simulation? Are you using a profile for max_cfl_u in inputs.in?

Try the following :
1. Add #include "parsing.h" at the header of your user_post.c, user_points.c and user_points_data.c files. Re-compile the udfs.
2. If you are running with a profile for max_cfl_u, switch to a single,constant value to see if the case runs. This will help diagnose the issue.
3. We always recommend switching to a recent version of CONVERGE. v2.3.10 is very old . We are currently at v2.3.35.

Hope this helps,

Sincerely,

Thank you! I'll check the case according to you suggestions.
