Can you be more clear. You have two solids that you want to assembly mesh. Are the two solids in different groups? You could hide one of the solids and go to Tools--FEM---Node--Associate--Solid--Apply in List A and add to group. Then select elements associated with these nodes typing 'lista' in...
Please explan your problem in more detail. What do you mean exactly by using rivets? Do you want to represent them in the fuselage or want to simulate them?

Contact is going through. Equilibrium is a more difficult issue. Did you try much more refined mesh? Also, if contact is going through dont use Contact Damping instead use *Static, Stabilize. It sometimes might help achieve equilibrium. Yes, look into the quasistatic analysis section in...
In increment three look at the message file. Is abaqus cutting back because it cannot resolve contact? maybe severe discontinuity iterations? or it can resolve contact but cant achieve equilibirum? you could try and put some damping in step three either for the contact or just for the step and...
ANSYS has a coupld of examples. But basically after you model your workpiece and electrode you will either apply voltage at the electrode areas or current at some nodes. You will mainly need the thermal conductivity and electrical resistivity of the two materials. This might be a function of...
The problem is involved. If you are interested in the joule heat and want to simulate as closeley then thermoelectric analysis would be appropriate. In this you can either apply voltage or current at the nodes which will result in heating. I think you might also need to consider element birth...
I have done some coupled field thermoelectic analysis with applied voltage instead of current. If you describe your problem I could try and help you if I can

try the following command in the the command line editor in CAE
>>> m = mdb.models['Model-1'].setValues(noPartsInputFile=ON)
(assuming 'Model-1' is your model name)

Or you could do a combined analysis. Input the non-linear material stress strain curve for the material. First step cold form it and second step apply additional loads.

True, You should have NLGEOM. I dont know if this will help as much because a rigid body simplifies the analysis-- you might want to try doing the analysis with a deformable body in pkace of the rigid body but put the stiffness of the body really high.

Hi,
There is a similar problem of a rigid cylinder contacting a foam surface in manual. Take a look at that. Try using a small amount of friction. In some problems that I have done, it converged better with friction!!. Also maybe start with just the elastic material first and see if it converges...
