Getting Started

[stu]

I'm just starting work on fem and trying to get ElmerGUI running on a Mac. I'm using the 'Getting started with ElmerGUI' tutorial example 'angle3d.grd'.
When I start the solver it runs briefly and crashes - the solver log says only 'Reading Model....' Console log is shown below. Also attached is the summary screen for the project.
I'm running OS X 10.6.4 and the Elmer solver is 5.5.0.

Is anyone aware of a problem that might cause this or am I doing something incorrectly?

Thanks for any assistance.

Hi Stu,

ElmerSolver seems to die very early while just initalizing stuff. Don't really know what that is about.
Could you get a terminal session, 'cd' to model folder and do
/Applications/ElmerGUI.app/Contents/bin/ElmerSolver
and show the us the output?

Also if you could tar+gz your model directory and attach it to a forum post we could try it to
figure out whether it is something about your model setup, or the Mac Elmer installation...

Where did you get the Mac binaries, btw ?

Hi Stu

Did you get your binary from:
http://www.trueflaw.com/pub/elmer/page3/page3.html

Unfortunately the latest therein is from revision 3054 and as we are currently on revision 4613 there has been around 1500 commits and some of those may have corrected your problem. Unfortunately I do not know of any more recent Mac version.

Thanks for the prompt responses. I had assumed that the binary at trueflaw.com was fairly current - on further examination it turns out that it was compiled for OS X 10.4 which was back in the PPC days, so it's not too surprising that it doesn't work well on an Intel Mac and 10.6. I have machines running 10.3, 10.5 and 10.6 but no 10.4 : (

So other than rolling my own for 10.6 (which I will look into), do you have a recommendation for a *nix flavor where Elmer is well supported?

Thanks again -

Stu
