Errors during voxeling

I have a very small wearable device with 4 different materials in the design. Using Bounding Box 9x subgrid, the number of cell was 3.388Gcells.

In the voxeling process, there were errors in the console:

Error : Dynamic exception type: class std::exception
std::exception::what: Unable to allocate memory for bit matrix

Error : Dynamic exception type: class std::bad_alloc
std::exception::what: bad allocation

Error : Dynamic exception type: class std::bad_alloc
std::exception::what: bad allocation

Error : Dynamic exception type: class std::exception

Error : Dynamic exception type: class std::exception
std::exception::what: Unable to allocate memory for bit matrix

Error : Dynamic exception type: class std::exception
std::exception::what: Unable to allocate memory for bit matrix

Does these error messages indicate that the machine is running out of memory?

Yes, bad alloc means the memory could not be allocated. Try to reduce grid size, and ensure your subgrid is substantially smaller than the total computational grid.
