A remeshing rule describes all aspects of your adaptive meshing specification:
A remeshing rule works in combination with the edge seeding, element type, and meshing method to determine the mesh at a particular adaptivity iteration. Remeshing rules are stored in the model database and are maintained between sessions. To create a remeshing rule, select Creating a remeshing rule. from the main menu bar. For more information, seeYou can define multiple remeshing rules over multiple regions of your model. If you apply multiple remeshing rules to the same region of a model, Abaqus/CAE applies a conservative element size specification, and the rule that defines a finer mesh at a particular point takes precedence. If you assign a remeshing rule to a dependent instance, Abaqus/CAE remeshes the original part and each dependent instance of the part inherits the same mesh. Abaqus/CAE requests error indicator output variables in every job that you create while a remeshing rule is active. The remeshing rule has no effect on the mesh during the first job. However, during the first job Abaqus uses the remeshing rule to calculate the error indicator output variables. In subsequent adaptive remesh iterations the remeshing rule augments your mesh size specification to produce a mesh that attempts to optimize element size and placement to achieve the error indicator goals described in the rule. |
