Hello everyone,

I created a model in Grasshopper and analyzed it in Millipede FEM. Although my model has a symetric shape, the results of Millipede show the stress pattern in an asymetric way. I don’t know the reason behind it.I think there is a mistake in my model or Millipede definition. Can you help me, please?

Thanks in advance
