Hi all,

I'm seeing fairly frequent errors when trying to start the transient solver with an overset grid:

*** glibc detected *** /usr/local/ansys/v192/fluent/fluent19.2.0/lnamd64/3ddp_node/fluent_mpi.19.2.0: free(): corrupted unsorted chunks: 0x00000000075e7a00 ***
*** glibc detected *** /usr/local/ansys/v192/fluent/fluent19.2.0/lnamd64/3ddp_node/fluent_mpi.19.2.0: double free or corruption (!prev): 0x00000000068332f0 ***
*** glibc detected *** /usr/local/ansys/v192/fluent/fluent19.2.0/lnamd64/3ddp_node/fluent_mpi.19.2.0: corrupted double-linked list: 0x00000000073beaf0 ***

I am running on my university cluster with version 192. Previous times i've had the issue I have solved it by randomly playing with the memory allocation/number of nodes and cores selected until it worked. But it is very frustrating and time consuming. My cluster tech support says it is an issue with ansys, has anyone else had this issue? Running steady state is fine, so I know the case file is not corrupted
