Problem with building 3ddp UDF in Ansys FLUENT 16.2

SPH_CFD · July 18, 2016, 11:46

Dear all,

I have a strange problem. First, I run 2D with UDF (2ddp_host and 2ddp_node), everything is built and run as normal.
After that I start 3D model with the same UDF and copy libudf from 2D cases with adding 3ddp, 3ddp_host and 3ddp_node. I do not understand why I cannot build it and get this message

make[1]: Entering directory `path/libudf/lnamd64/3ddp'
makefile:14: user.udf: No such file or directory
make[1]: *** No rule to make target `user.udf'.
make[1]: Failed to remake makefile `user.udf'.
# Generating udf_names.c because of makefile

I try the same folder with 2ddp is OK.

Could you give me advices about this problem?
Thank you in advance.

you gotta compile it again for 3D case.
