Hello, everyone!nI try to do a simulation with CFX and using a user Fortran subroutine in Linux machine. When I compile and lance CFX solver, I obtain this error. nmy subroutine integral a function from 0 => +infini. When I use integral from 0.2 => +infini it works normally but when I integrate from 0 or 0.1 => +infini it gives me this error. (I tested my integral in online compiler without CFX and it works normally)nParallel run: Received message from slaven -----------------------------------------n Slave partition : 14n Slave routine : ErrActionn Master location : Message Handlern Message label : 001100279n Message follows below - : n n +--------------------------------------------------------------------+n | ERROR #001100279 has occurred in subroutine ErrAction. |n | Message: |n | Signal caught: Segmentation violation |n | |n | |n | |n | |n | |n +--------------------------------------------------------------------+nn Parallel run: Received message from slaven -----------------------------------------n Slave partition : 14n Slave routine : ErrActionn Master location : Message Handlern Message label : 001100279n Message follows below - : n n +--------------------------------------------------------------------+n | ERROR #001100279 has occurred in subroutine ErrAction. |n | Message: |n | Stopped in routine FPX: SIG_HANDLER |n | |n | |n | |n | |n | |n +--------------------------------------------------------------------+n n +--------------------------------------------------------------------+n | ERROR #001100279 has occurred in subroutine MESG_RETRIEVE. |n | Message: |n | Stopping the run due to error(s) reported above |n | |n | |n | |n | |n | |n +--------------------------------------------------------------------+nn +--------------------------------------------------------------------+n | An error has occurred in cfx5solve: |n | |n | The ANSYS CFX solver exited with return code 1.

What does the subroutine do? Do you observe the issue on different compilers? n

Hello DrAmine!nThanks, we find the problem, it was in the cluster (Linux machine). When we try the integral in windows machine, it works normally. But in Linux it does already not work, has you an idea to resolve this?n

Did you recompile the FORTRAN code on Linux? Which flavour of Linux? n

Intel 2019.3.199 FORTRAN (for custom solver modeling using User Fortran) is the official supported Fortran Compiler for Ansys CFX.n
