Contact Convergence

Hello All,

 

I am relatively new to use contacts and running non-linear analysis in Optistruct. I am facing convergence issues in my model with static friction contact.

 

I have used NLPARM + Non Linear Quasi Static analysis to run the simulation with friction contacts.

 

In the picture you will see that the body in pink is tetra mesh with aluminium and the yellow component is penta mesh with titanium. Load is applied on the titanium and contacts are defined between.

 

I haven't used any PCONT cards here as I have not much experience with it.

 

Here the yellow component being the harder component and the component with the load has been set as the master. Both the sets 'Pink' & 'Yellow' here are element sets

 

The Y distance between the yellow and the pink component is 5.004e-03mm.
