Structural Topology Optimization using the Genetic Algorithm

I ran into a similar (completely maddening) situation when using an Ubuntu 12.04 LTS guest with Vagrant configured to create a private network.

I don't recall the exact cause of the failure, but switching to the virtio networking drivers has completely solved this issue for me.

  config.vm.provider :virtualbox do |vb|
    vb.customize ['modifyvm', :id, '--nictype1', 'virtio']
  end
