  1. Making a Medial Object Useful in an Engineering Simulation Context

  2. Medial Object is the Gateway • MO is not the end goal for engineering simulation but a means to get to other capabilities or functions • Mid-surfacing • Dimensional reduction • Mesh sizing • Proximity information • Simulation related property extraction • Feature recognition • Feature based actions

  3. Medial Object is the Gateway MO is a reduced dimensionality representation So if we get an MO we are good to go !!! Not so much - the MO is just the beginning of the journey

  4. Medial Objects have artifacts • MO is a reduced dimensionality representation • A “proper” MO has “artifacts” that are mathematically correct but confusing and possibly disruptive to the function we are building it for • Flaps • Medial Surface flipping (& associated transitions) • Junction smoothing • Too much dimensional reduction • More… • What is an artifact for one function is a requirement for another

  5. Medial Objects need to be “transformed” • MO needs to be transformed to fit the function it was created for • Extensions to remove flaps • Constant surface orientation through Medial Surface flipping & associated transitions • Squaring up junctions • What to do when the medial object has no surface • May require more info • MO topology and not just geometry • callbacks to original geometry • an MO of the MO

  6. Medial Objects need to be “transformed” • MO transformation to fit the function needs to be fully automatic or trivial • Conceivable with a few rules for simple objects • Unclear on complex “real-world” objects where there are multiple interacting artifacts

  7. Medial Objects need to be “transformed” • We then have four choices for using MO in an Engineering Simulation context • Limit MO to use as reference information only • Useful in some functions • Not enough for most use cases • Function based MO transformation tools • As we approach robust MO creation we need to shift effort into researching function based transformations • An MO is not a mid-surface usable for meshing or costing or CAM • Function based tools that “think” MO but never build one • There are some available and more coming • A combination
