I have seen flow act crazy when trying to run because of permissions. Have you tried doing this logged in as admin?
Hi, thanks for your reply.
My user login is the only one on the computer, which is an administrator account.
I have tried reinstalling the graphics driver via the solidworks site (someone else on here had a similar problem and that solved it for them).
No luck for me though!
I also hadn't activated the software before but now I have. Still the same problem.
hi matt, so you have the 2012-2013 version installed? can you go to help > about solidworks and tell me what version and service pack it says you're running? it will be the first and second lines.
my first thought is, where are the files? we've seen some issues where files are located in a sync'd dropbox or vault of some sort cause this issue.
my second thought is, do you have office installed? if so, what version/service pack? 32bit or 64bit?
my third is graphics card driver. with no files open, can you go to tools > options > systems options > performance > enable "software opengl" and see if the problem happens again. (use your simple example like a tube with flow on one end and pressure on the other)
if everything here checks out, i'd go with timothy on an install problem. i'd get everything uninstalled (through remove a program, clear all old directories, clear the reg..etc using a guide from the reseller you work with) and then resinstall and make sure your AV and AS tools are disabled and that you have admin rights and that UAC is disabled.
Office is not installed on this computer and the files are from my documents.
However I have tried your suggestion to select 'Open GL' and the solver now runs and doesnt crash SW!
So thank you very much for helping me fix that issue!
hi matt, glad i could help. cylo had the same issue: https://forum.solidworks.com/thread/64145?tstart=0
sounds like there might be something wrong with the ATI cards and Flow Simulation.
That graphics card should work. So maybe try some other drivers and make sure your systems is completely updated with firmware..etc.
You might want to check with your CAD admin to see if you can get the 2013-2014 version when it is available to see if that version works better. But your config should work.
