Getting the boundary object from the voxelized domain

[mojtabaAmiraslanpour]

Hi,

I am trying to get the boundary of the voxelized domain in the pipeflow example. I use the getBoundary function to do that:

TriangleBoundary3D<T> boundary = voxelizedDomain->getBoundary();

I don't get any compilation errors but I get the bad allocation error when running the code:

(PipeFlow) Starting simulation...
terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

I mentioned that here, the boundary is defined by its constructor but I am not sure how to get it on the outside.

Hi,

If you don't need it run-time, you can use threshold inside paraview and set the threshold as 0-0. This will give you the fluid nodes. If you set threshold 1-1, you'll get the solid nodes.

Thanks, Eren, but I actually need it in run-time. I managed to get it though.
