When I first run the Inviscid_Bump, there are some errors:

orted: symbol lookup error: /usr/lib/x86_64-linux-gnu/openmpi/lib/openmpi3/mca_pmix_ext3x.so: undefined symbol: pmix_value_load
[DESKTOP-823G5TH:17385] [[INVALID],INVALID] ORTE_ERROR_LOG: Unable to start a daemon on the local node in file ess_singleton_module.c at line 716
[DESKTOP-823G5TH:17385] [[INVALID],INVALID] ORTE_ERROR_LOG: Unable to start a daemon on the local node in file ess_singleton_module.c at line 172

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

orte_ess_init failed
--> Returned value Unable to start a daemon on the local node (-127) instead of ORTE_SUCCESS

It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):

ompi_mpi_init: ompi_rte_init failed
--> Returned "Unable to start a daemon on the local node" (-127) instead of "Success" (0)
--------------------------------------------------------------------------
*** An error occurred in MPI_Init
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this communicator will now abort,
*** and potentially your MPI job)
[DESKTOP-823G5TH:17385] Local abort before MPI_INIT completed completed successfully, but am not able to aggregate error messages, and not
able to guarantee that all other processes were killed!

I'm new to SU2 software and CFD and I don't know how to solve this problem. Thank you for your help!

Looks like openmpi was not correctly or completely installed. Please reinstall openmpi and make sure it works correctly by running a simple openmpi test.

The problem is indeed openMPI. The 5.0.0 version I installed before may be unstable.Later, after reinstalling the now stable distribution (4.1.5), the computation was fine.Thank you for your help
