Error Message "Insufficient space for array LNOD"

Hi!

I’m running a transient simulation with a moving mesh with approximately 950k elements on 6 cores.
And it works fine for the first 30 time steps but then it crashes and it gives this error message:

ERROR #004100008 has occurred in subroutine FINDL.
Message:
Insufficient space for array LNOD.

Anyone has some idea of what the problem can be?

Am I using to many cores for a to course mesh?

There is no sufficient memory for an internal array.

Try providing more memory at the start of the run. In the ANSYS CFX Solver Manager check for the memory overrides/factors.

Hope the above helps,

Thanks for a quicke response.

Is’t this setting you mean?

A quick update about the problem, changing the memory overrides/factors didn’t help.
But got a reply from Ansys saying: “Switch to Independent Partitioning (coupled is the default/Automatic)” and this seems to work for me.
