Iunderstandd you run NX Advanced Simulation V8 + NX NASTRAN, ok?.
In order to be able to solve the linear contact problem using "surface-to-surface" contact (SOL101) remember you need to setup the model as 3-D, ie, you need to mesh with solid elements CETRA/CHEXA. In the picture you post I do not see if the model is 2-D or 3-D.
If the model is meshed with 2-D elements (the problem could be a typical case of PLANE STRESS, PLANE STRAIN or 2-D Axisymmetric body of revolution) then not possible to use the linear surface-to-surface contact capability, instead you will need to solve the problemnonlinearinar (SOL106) and use slide-line contact.3-D Slide Line Contact Analysis -------------------------------------
Slide line contact lets you model interactions between two deformable bodies. One of the deformable bodies is called the master and the other is called the slave. The modeling of interaction requires that you define contact regions in terms of slide lines. You may specify as many slide lines as you need.
A slide line contact region consists of a master line and a slave line. A master line is a list of grid points in the topological order on the master body. A slave line is a list of grid points in the topological order on the slave body. The grid points on the master line are called the master nodes, and on the slave line are called the slave nodes. A line segment joining two consecutive master nodes is called a master segment. Thus a master line, in general, consists of number of master segments. A minimum of one master segment consisting of two master nodes are required for the master line. Similar to master line, a slave line, in general, consist of a number of slave segments. However, a slave line may not have any slave segments; it may have just one slave node.
Tale a look to the NX NASTRAN HELP LIBRARY to learn more about sline line contact, or better solve the contact problem using solid elements, then you will be able to run a linear static (SOL101). But have in mind that liappliestact applyies to small displacements problems, if SLIDING exist then your linear static contact results will be meaningless ....
