Midplane Meshing in Autodesk Simulation Mechanical


Meshing a model at the midplane location that is formed exactly at the center of inside and outside surfaces of the model to be meshed is called Midplane meshing. This type of mesh is used when the geometry of a model is symmetric about its inside and outside surfaces. The midplane mesh is generate by using plate elements instead of brick elements. Therefore, it is recommended to used midplane mesh for thin components having uniform thickness throughout. The plate elements treat bending more accurately than the brick elements. Below figure A shows a model before creating midplane mesh and Figure B shows the same model after creating midplane mesh.

  1. I don't know the term 'solidwork' but I assume you mean objects of significant size (sometimes called extended objects, as opposed to point objects).. . The centre of mass (CoM) of a structure is the same as the centre of gravity (CoG) for all practical purposes. CoM and CoG are often used interchangeably though there is a subtle difference in meanings.. . An object may have a huge number of separate parts, each with its own weight. For static problems (no movement) the combined effect of these separate weights is the total weight and can be thought of as a single force acting at a single point; the point is the centre of gravity.. . If you have to do moment (torque) calculations involving an extended object, you only need to consider one force if you know where the CoG is; you don't have to deal with the weights of all the separate parts.. . There's a video in the link which might help. It also explains s the difference between CoG and CoM.
