polyTopoChange vs directTopoChange
 

Hi foamer,
I'm having a hard time investigate the code of InterDyMFoam solver in OpenFoam-1.6-ext. Have you guys ever tried the dam break with obstacle tutorial in this version, the dynamic refine mesh algorithm doesn't work. However, when comparing the code with the InterDyMFoam solver in version 1.7.1 ( which successfully simulating previous mentioned tutorial ), i guess the problem might locate in the different topology changer mechanism OpenFoam uses. I've been searching for document on this subject. Do you guys have any recommend ?
