Significance of contact methodology in Radioss Bulk Data Format

Hi,

I wanted to know about how a contact methodology will effect the results.

For eg. I have two solid blocks, one resting over each other. They have a contact surface in between them.

The two blocks have two different properties assigned and I made sets of elements using properties.

Now I have two sets and assigned contact between them. On reviewing all the elements of block 1 are in contact with all the elements of block 2.

In second case I just made the elements on the interface to be in contact and not the whole elements.

What is the effect of this on results.

As it is easy to assign sets using properties and thus contact can be made in an easier manner.

 

What  I am thinking is like , this will not effect if I am going for a linear static simulation but the computation time might increase. However the results and computation time might be drastically effected in case of non-linearity due to contact like friction etc.

 

Kindly let me know for the same.
