Examples for Linear Gaps modelling.

ron.kunz
Dear all,
I would like to study some examples with linear gap elements. We don`t have SOL400 available and to have a work around for i.e. objects touching or near eachother.
Could you provide wtih some examples or give location of study material? Thanks.

    You don't need SOL 400 to model contact. Linear Contact (for general contact modeling) has been part of MSC Nastran since 2010. It uses the same input and iterative solution method from SOL 400 in SOL 101. The only limitation is small sliding assumptions (consistent with linear analysis/small deflection assumptions - linear gaps have them too). In addition, you can use Touching or Glued contact (or a combination of them). Compared to linear gaps, this method is easier to setup, easier to visualize (and understand) and has fewer limitations.
    I strongly encourage you to investigate Linear Contact before spending time on 'linear gaps'.
