Hi,

I am new to OF. I intend to use openFOAM to do some resistance estimates of various hull forms. I started by running DTCHull tutorial using ./Allrun in order to get familiar with post processing and case set-ups. After running the case, I accessed the post processing folder and the file force.dat reads 0 for each time step which is clearly wrong. Has anyone encountered the same problem? Is there any data that needs to be modified before running the case? Perhaps I have missed something?

Thanks

Hey.... yes you are missing a command... instead of giving ''snappyHexMesh'' command just give ''snappyHexMesh -overwrite''. Using this command you will be overwriting the files in constant folder with all the files for faces etc and then it would start giving the values of Forces because in that case it takes into account the Hull otherwise not
