Hi,
I am doing simulation of a scroll compressor in CFX.I have built my mesh in Twinmesh. A mesh is generated at intervals of one degree. I'm using transient calculation.

When the revolution speed is 1000rpm, CFX can calculate correctly. But when I increase the revolution speed to 2000rpm, en error will always occur at about 120 step.

The warning message is like：
ERROR #004100018 has occurred in subroutine FINMES. | | Message: | | Fatal overflow in linear solver.

I have tried to use the result of the 1000rpm calculation as the initial value as the 2000rpm calculation, but the error would still occur.

I wonder what's the reason of the problem and how can I solve it.

Thanks in advance!
