Dynamic mesh – motion history issue

      Hi. I am running a simulation of a wind turbine with dynamic meshing. I am writing mesh motion and torque/moment. I am facing 2 issues:

      1. After the initial 10s of simulation, the number of time steps being recorded in torque and mesh motion files are different; I get more data points in torque than mesh motion. Torque file divides time into more parts than mesh motion, though the total time remians the same. How can this be resolved?

      2. In mesh motion history file, when the time reaches 10s, the significant figures after decimal decreases by 1 and than I see lots of time data which remains the same (same values). How can this be resolved?

      Please see below the torque and mesh motion history files for reference. Need help.

      Hello, 

      What is the dynamic mesh settings you are using? Can you try in the latest version (2022R2)?

      I am using SDOF without remeshing. I do not have access to any other version at the moment.
