Hello,
What is difference between boundary conditions in FEM? when we use viscose BC, absorbing BC and free field BC? What is difference between underground structure and surface structure in BC and when we use these BC for underground and surface?
Try to see this book:
and:
I appreciate that Dear Hayat
