Mesh coarsening
Web10 sep. 2024 · After performing the simulations using fine and coarse meshes, we observed that the mesh refinement slightly improved accuracy for < 1%, while the mesh coarsening decreased accuracy for < 5%. To decrease the accuracy more appreciably, the extra-coarse mesh grade was introduced by substantially reducing the number of integration points. WebIf the mesh contains anisotropic elements (for example, a boundary layer mesh), it is best to disable mesh coarsening to preserve the anisotropic structure. If you have selected to allow coarsening, specify the Maximum coarsening factor(a value of 5 by default) to scale the refined mesh size in the regions where refinement is not needed

Modern structures typically have complex geometries which can require hundreds of thousands of degrees of freedom (DOF). Even relatively simple structures may have bolted or welded connections between members which can be difficult to model without resorting to a fine FE mesh. The computational burden involved …
Webin a coarse-to-fine fashion by integrating the retargeting process with a mesh-coarsening pipeline. First, we propose a mesh-coarsening module that coarsens the mesh representations for better motion transfer.
