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 errorsFebruary 8, 2021 at 5:02 amKeyur KanadeAnsys EmployeeAs ANSYS Staff, we can not download attachments.

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.

If so, I would focus on that part.nThank You,nAnadinFebruary 8, 2021 at 12:10 pmRobAnsys EmployeePost 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. nFebruary 8, 2021 at 1:32 pmYasserSelimaSubscriberAs the error happens on initialization, it is the DEFINE_DPM_INJECTION_INIT function ...nProbably you need to initialize values in UDMI before using them. nFebruary 8, 2021 at 5:31 pmFebruary 8, 2021 at 5:34 pmViewing 8 reply threads
