Any Problems with Abaqus 64 bit version 1

[fruton]

Hello all,

I am planning on switching to 64bit abaqus 6.10, and I am wondering if any users have had any issues with the switch over. I am upgrading to Win 7 64 bit and checked my system is compatible with the Microsoft Win 7 compatibility checker. Main reason for doing this is to allocated more RAM to analysis work.

Any feedback appreciated.

Ive been running 64bit for quite some time on XP, SUSE Linux, and Windows HPC server with no issues associated with 64Bit. Good luck and be sure to post with your assessment.

Thanks, would I face any issues opening and continuing abaqus 6.10 and 6.9 models I have developed using 32bit and then switching them to 64bit?

It's been a while since I have run 32bit but when I made the switch I do not remember it being an issue. I would test on a copy of a model first though.

You may have issues restarting 6.9 analyses with the 6.10 solver. I don't think this is possible. Regarding 32/64 bit I've never tried switching between the two for restart anlayses so can't comment on that, opening existing results (e.g. odb files) shouldn't be a problem. I've never noticed any problems with 64bit and win7 (that weren't already there on other platforms of course).

Why win7 instead of linux? If it's a fem dedicated machine, linux give you a best MPI and use only 350KB ram instead of 1GB, and where developed before for 64bit architecture.
And it's free.

Thanks all, problem is, its not a FEM dedicated machine and I need to use it for everything else also. Plus I have never used Linux and would not have the time for the learning curve.

I'm running Abaqus 6.10.1 on Win7-64 and have't seen any issues.

I seem to get an error when I try to run an analysis saying "System error in contact tracking: the memory is not allocated with the right size", but I have run many analysis with the same memory settings. Does anyone know how to solve this? Thanks.

I seem to only get this problem when I run my contact with "finite sliding", it seems to run ok with "small sliding". But results and stress profiles seem less accurate with small sliding. By reading the abaqus manauals I see that finite sliding can sometimes make it more difficult to get a converged solution.
