Solve FE model error
Solve FE model error
(OP)
Hi,
I'm new to FE modelling and analysis in IDEAS.
When I attempt to solve an FE model (having set boundary conditions, loadings etc...) the following error appears:
"nbb.exe is not a valid NT application"
I'm running MS8 with NT4-service pack6A.
Has anyone else encountered this problem? or can anyone provide any insight towards correcting it / getting around it?
Thanks in advance for any help.

Obviously MS8 is supported by NT, so where's the problem???
Do you, or anyone else, have any other suggestions?
Cheers.

Try this though, it all works fine for me now
go into your display properties, click on the settings tab and then the advanced button. Then manually turn down the level of hardware acceleration that your graphics card supplies. It should work if it is turned down a couple of nothces, if not all the way.
Although technically i don't fully understand why this works, i think it is something to do with disabling the direct draw and direct 3d applications (affected by directX).
Hope this helps..
don't forget to turn performance back up afterwards when not using FEA otherwise other graphically rich applications will suffer a drop in performance.

Gave it a go, unfortunatly my situation has not changed, I still stumble at the same point with the same error.
What operating system were you running when this worked for you??? Was it NT4???

As a result of your last post I spent some of the weekend setting up a fresh partition with win2K Pro with you fix applied.
I still get the same error, albeit expressed in a slightly different fashion. All the latest drivers and service packs are loaded.
I've done some extended searching and reading, and located some additional tips on memory etc, my graphics card (Matrox G550)also gets a mention and the fix recommended applied.
What puzzles me is, when I double click on NBB.exe fron NT, XP or 2K it always produces an error. Generally if you double click an executable it either runs, produces a DOS box or does nothing !!! Which makes me think I have a dodgy file.
Do you think I could ask you to click on yours, don't have any programmes open, and report back.
Thanks

I'll try and run NBB.exe as you've asked.
