      Hi,nI am running a steady state simulation with unsteady DPM.nI wrote an UDF that, at the end of the simulation, should give me a .txt file with information on the particles that hit a specific wall (the one I put my UDF as BC for the DPM).nThe job gets interrupted when the DPM starts the calculations and in the error file I receive:n==============================================================================nNode 1: Process 22529: Received signal SIGSEGV.n==============================================================================n*** Error in `/appl/ansys/2019R2/v194/fluent/fluent19.4.0/lnamd64/3ddp_node/fluent_mpi.19.4.0': double free or corruption (!prev): 0x000000000730fae0 ***nnCould you please give me some hints on what happens?n

      Does it work without the UDF? n

      Yes, it works without UDF.n

      If you run the model for a while then turn on the UDF what happens?.ote, for UDFs it's possible to write grammatically correct code but still create something that doesn't work due to a data mismatch or incorrect call. n
