Path-- help

[Chen1]

Hello there,

I am modeling an underground mine, so i delete some elements to simulate removing the ore. I need to talk path to see the variation of stress near the excavated parts.

I took node path which went through the excavated parts of the model, in other words, the path went through voids, i see that stress field is continuous and the magnitude of the stress is not zero at these excavated areas (voids). Can somebody help me to fix that problem.

So i need to see discontinuity in the stress field at the excavated areas.

Thanks
