Using distributed resistance materials in a 2D axisymmetric simulation

Hi all. 

 

I am currently trying to run a axisymmetric simulation (following the proper procedures such as aligning with Y-axis) with distributed resistance materials included. However I keep getting " The Analysis has stopped because the solver exited unexpectedly".

 

I have tried using the flag 'no_difu_tensors' set to 1 to revert back to the old ways with no success.

 

It runs fine when not specifying axisymmetry though, however i kinda need the axisymmetry to avoid having to run 3D simulations.

Best regards

I don't have to use axisymmetric analysis much but when I had to, I have faced similar problems with axisymmetric cases earlier. If you are hell bent on using axisymmetric and avoid full 3D, how about making a small wedge (3-5 deg) and use symmetry at both faces? It will be useful here if you keep the wedge "one element thick" to avoid integration errors. Always economical than using a 90 deg wedge etc...

 

But of course if you are able to sort out the 2D axisymmetric, it is always the best approach...

I have had to resolve to simulate wedges too before this. Somehow my simulation runs fine now in 2D with axisymmetry. Not really sure what I did though...

Paul,

I"m glad you did get it working.

When you get the solver exit unexpectedly next time i would suggest taking a look at the status file to see if it outlines what might be causing the error.

Let us know if you run in to further issues

Thanks, I will try to remember that!
