Hello,
I’m running rather long FSI simulations using OpenFOAM and preCICE. Although I use the adjustableRunTime
in the OpenFOAM configuration, OpenFOAM starts to name the solution directories according to an accumulated time step, e.g., 8.100000000001 instead of 8.1. Also, the time precision is with 12 already selected rather high in OpenFOAM. Is there an opportunity to prevent this?
Background: I use a script to postprocess my data and the unexpected naming destroys the functionality of the script.
I also noted that preCICE writes the time to a precision of 16 digits in my watchpoint file. Here, the time is also not exactly the specified time-window-size, i.e., 0.0810000000000001 instead of 0.081. I know that preCICE has the option to specifiy <time-window-size valid-digits="" time-window-size\>
in the config file. But what is the impact. Does it just affect the writing of data or could it lead an undesired subcycling of participants due to truncated time-step sizes?
Thanks in advance!
