Hello,

Greetings! I am trying to simulate annular flow in a tube. I am using UDF for mass, momentum sources and to initiate droplet injection. Here udf.h and sg_film.h have been used. I am also using UDMI . I have no problem to compile UDF in fluent. I am getting following errors

Hello ,Greetings! I am trying to simulate annular flow in a tube. I am using DPM(Discrete phase modeling) and EWF (Eulerian wall film) along with UDF for mass and momentum source. I compiled UDF perfectly and set all the values and parameters. But, when I am trying to initialize the solution( standard initialization from all zones) , I am getting following error,999999: mpt_accept: error: accept failed: No error999999: mpt_accept: error: accept failed: No error999999: mpt_accept: error: accept failed: No error999999: mpt_accept: error: accept failed: No error==============================================================================Node 0: Process 18384: Received signal SIGSEGV.==============================================================================999999: mpt_accept: error: accept failed: No error999999: mpt_accept: error: accept failed: No error999999: mpt_accept: error: accept failed: MPI Application rank 0 exited before MPI_Finalize() with status 2 The fl process could not be started.I am using structured hexahedral mesh with 260000 elements and 265521 nodes.

nYes, please use UDMI before compiling UDF if you are using it in UDF. nRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn

Hello Keyur,nThank you for replying quickly. Here I have attached the photos of code I am using. Please have a look.nAnadin

We cannot help debug UDFs or write UDF.nIf you are using UDMI, please define before compiling UDF. nRegards,nKeyurnHow to access Ansys Online Help DocumentnHow to show full resolution imagenGuidelines on the Student CommunitynHow to use Google to search within Ansys Student Communityn

Hello Keyur,nIs there any way to check where exactly I am doing mistake in UDF or the reason of error? If so, I would focus on that part.nThank You,nAnadin

Post the code, whilst we (Ansys) aren't going to debug it we can have a quick look. Other community members are free to do more if they wish. n

As the error happens on initialization, it is the DEFINE_DPM_INJECTION_INIT function ...nProbably you need to initialize values in UDMI before using them. n

Hello Rob,nHere I have uploaded the code for quick review. Please have a quick look over it and suggest some guidance.nTotal number of UDMI is 12. Am I correct?nThank you.n
