Querry on Adaptive Remeshing and not ALE Adaptive Meshing in ABAQUS

[chindan]

This maybe a very basic question and i would appreciate if anyone could answer this. Is there a possibility to write a user defined function for ADAPTIVE REMESHING. From the manual i have found out that Adaptive remeshing is available only for Abaqus/Standard analyses submitted from Abaqus/CAE. I would like to use this for dynamic problems and also for using it in /Explicit analysis. Is there another mesh generation software which links with ABAQUS.

Any suggestion on how to implement adaptive remeshing in ABAQUS would be highly appreciated.

Interesting question. Unfortunately I don't think there is a way to write a user-defined function for adaptive remeshing. You can probably reproduce some of the functionality by direct coupling with an external mesh generator, such as TrueGrid (http://truegrid.com).

I am curious: what problem you are trying to solve. Do you really need adaptive remeshing? or are you looking for "ALE adaptive meshing" which is a completely different technique that is quite useful and available in ABAQUS/Explicit.

Thank you Jorgen for your reply. I shall look into the external mesh generator which you have mentioned TrueGrid. I am trying to simulate 3-D machining and for this i do need adaptive remeshing also coupled with the ALE Adaptive meshing for smoothing. There is a commercially available software such as DEFORM3D or even ThidWave which can simulate machining but these do not provide enough user defined functions and hence my aim is to be able to use ABAQUS for simulating 3-D machining.

Thank you for your help.
