In many cases you will want to transition between automatic and manual use of adaptive remeshing. Some examples include:
You must keep the current Abaqus/CAE session active for automatic remeshing to occur between analysis jobs. If you exit Abaqus/CAE and start a new session, you must use manual remeshing to remesh the model.
You start an automatic sequence of jobs, but a machine problem (such as a full disk) interrupts the analysis prematurely. You can restart the analysis manually and then continue it in a fully automatic manner. Variations of this case include an analysis ending because it failed to converge or an analysis ending because you terminated the job during a particular iteration.
You can experiment with sizing function parameters and remesh your model manually until you find a set of remeshing rules that creates a mesh that appears to be responding actively to your variables of interest. When you are comfortable with your remeshing rules, you can switch to automatic mesh adaptivity and complete a specified number of analysis iterations.
The mesh generated by the automatic mesh adaptivity procedure converges to an acceptable configuration. You can now modify the loads applied to the model and perform an additional manual iteration that makes a minor meshing adjustment to compensate for the new load.
You can transition directly between automatic and manual mesh adaptivity. To transition from automatic to manual mesh adaptivity, you enter the Mesh module and select Adaptivity
Manual Adaptive Remesh from the main menu bar and remesh the model. You then return to the Job module and submit the job for analysis. Conversely, to transition from manual to automatic mesh adaptivity, you create an adaptivity process in the Job module and submit it for analysis.
