### The coupling methods - ScienceDirect

2016-1-1u2002·u20023.2.1. Direct matrix assembly strong coupling method. If the physics models involved in the coupling have no common degrees of freedom (DOFs), but the coupling phenomenal can be expressed as matrix form as shown in Equation ; then the DMA method can be applied.
