Transient simulation and sliding mesh problems

alige

Hello! I have two questions about transient simulation and sliding mesh: In Fluent help 26.18.1 , it is said that :" Note that gathering data for time statistics is not meaningful inside a moving cell zone (i.e., a sliding zone in a sliding mesh problem) " but if I want to get the information of some points, which are fixed points in inertial coordinate but in a slinding zone in CFD simulation, how to do with them?

I have tried to write the information (such as pressure velocity) to a file after each time step ,but for about 500 or more points ,this process is very time-consuming especially in fluent's parallel operation. could anybody give some advice? thanks!
