Multi component analysis
 

Hi, I'm a final year student in my university doing my final project on 3-dimensional analysis and I have a few problem that haven't been solved which includes the meshing of multi component airfoil. First of all, can I have a brief explanation on multi component analysis? What is the advantage and disadvantages? Are there any alternative simulation types? What are the limitation? and What kind of initial condition that needs to be set? I hope any of you can help. Thanks in advance.
