Reduced order modeling

In Solfec-1.0, in the finite element context, it is possible to reduce the size of the per–body algebraic systems by applying reduced order or modal simplifications. Both of these are combined with a body–level co–rotational approach in order to incorporate large rigid body rotations – relevant in the multibody context. The details of this can be found in the technical report TR1 and in this blog post. Currently available examples of this functionality include:

• Rotating bar
• Pipe impact
• 81 bricks array
