ERROR: internal error: cmv cannot match polygon 1

Hi,

I'm runing a transient model for the compression chamber with the suction and discharge valves dynamics.

The suction valve should open 3 times, but everytime that this valve closes for the second time this error shows up:

"There are 331670 active cells in the domain
JOB ABORT invoked by rank 1:
ERROR: internal error: cmv cannot match polygon 1
job aborted:
[ranks] message"

Can you help me to fix this error?

Hi Clara, are these valves' movement prescribed or by FSI?

Hi,

I prescribed the movement of these valves by udf, at "reed_profile.in" file.

I already changed the CFL velocity coefficient, but then the error became the CFL number...

Do you mean you are using reed_profile.in in boundary.in to specify boundary motion?

If you are using UDF, which one are you using?

I think the fastest way to solve your problem is to send the case files to support@convergecfd.com. Thanks!
