Foam::error::printStack in interDyMFoam when changing the floatingObject case
Hello everyone,
I am trying to change the floatingObject case with interDyMFoam by openFoam 2.3.0.
The only change that I made was simply stick a turbine into the box. (I use snappyHexMesh to get the mesh done)
I can get the interDyMFoam running, but it get the error message very quick.

Can anyone tell me what's the error message means? Thank you so much. |
