Hi!

I am getting a strange error in the initialization of the solver. I have never encountered this error before, and I have no more ideas on how to solve it.

I am using Ansys CFX 16.1
The error occurs in the partitioning part of the solver.

The geometry is relatively large (~85 million elements)
So I have tried to use the "Large problem partitioner", but that didn't help.

Do you have any idea on how I should address this problem?

Here is a draft from the out-file:

That certainly is a weird error. I would try:
* different partitioning algorithms
* doing a partitioning only run and write a partition file. Try doing this on several machines.
* Check your def file is good - go back to CFX-Pre and check it and regenerate it.
