Purpose:

build the ID array of system dofs to apply displacement constraints

Synopsis:

[csdof,sid]=fe_sdofID(discons,ndof,nnode)

Variable Descr iption:

csdof - the number of system dofs after constraints applied

sid - ID matrix of system dof formatted as nnode*ndof

discons - matrix record the node of displacement constrain

ndof - number of dofs per node

nnode - number of nodes in system-Purpose:

　　　build the ID array of system dofs to apply displacement constraints
