On Max Number of DOFs
On Max Number of DOFs
(OP)
What is the maximum number of DOFs that can be handled by ABAQUS ? Is there any minimum machine memory requirement related to this number? Are there any computational ramifications (other than long computational time) that can be expected from using huge number of elements? As far as this point is concerned which is better FLAC or ABAQUS.
Thanks
Thanks





RE: On Max Number of DOFs
I have access to a Linux 64bit machine with eight processors and 32 gigabytes of RAM, what limits the size of analysis I run is the 32bit Windows OS PC (with 2GB of RAM) I use to pre and post process the models.
RE: On Max Number of DOFs
Comparing the two codes based purely on the max number of DOF's seems a strange measure. A comparison of material models, analysis techniques, pre- and post-processing and suitability for the job at hand would be more worthwhile?
Chances are that neither is necessarily 'better', but if you only need to do 2D geotechnical stuff, then FLAC may be the more appropriate tool for the job.

FLAC can handle 3D.. please review your info
Both can handle the features of my model but (Large Defo, Elastoplastic and others) But I am saying which is better when the size of the problem becomes very large
