Does BCData for moving mesh surfaces sync with actual mesh motion? #38

Closed spdomin closed 7 years ago

spdomin commented 7 years ago

Make sure that wall_velocity_bc and velocity_bc syncs properly with the actual time value. I think it does, however, someone make sure...

The uqSliding mesh is a good test as it uses wall functions. The following is also an interesting note in the code...

  // copy velocity_bc to velocity np1... (consider not doing this when a wall function is in use)
  CopyFieldAlgorithm *theCopyAlg
    = new CopyFieldAlgorithm(realm_, part,
                 theBcField, &velocityNp1,
                 0, nDim,
                 stk::topology::NODE_RANK);
  bcDataMapAlg_.push_back(theCopyAlg);

Looks like it may be fine...
