[COMSOL_Users] error 4100

[Saskia Roels]

hello everyone,

i am a new member of the group and just starting with comsol modeling. unfortunately i am facing my first problem already and i hope someone can help me.
as it is right now i am able to refine my mesh until a certain level and whenever i want to refine it more i get the following error:

Error: 4100
Failed to generate mesh for subdomain.
- Subdomain: 1
Internal error in advancing front mesher.

does anyone know what it means and what i can do to overcome this error?

Thanks a lot!
saskia.

Did you already solve this problem?
I'm really interested, because I have a similar problem:

Error: 4100
Failed to generate mesh for subdomain.
- Subdomain: 1
Failed to respect boundary element edge on geometry face.
- Face: 12
- x coordinate: -0.000213967
- y coordinate: -2.08624e-005
- z coordinate: 0.000269213
Internal error in boundary respecting.

thanks,

Paul

I got this message when I had a high-ratio (width-length) geometry. I
noticed that I could do two things. One is to make the mesh of the
geometry coarser. Or What I actually did was to reduce the ratio of the
geometry.
Though this is not really scientific, but it works for me.
Anyone knows why? please share.
Thanks

I'm really interested to see what could be a solution.
I have the same (or similar) problem:

Error: 4100

Does anyone know the route to solving this problem?

I know that this was posted long ago, but I thought I'd replay as new readers may still find this useful:

The advancing front mesher is a new feature of comsol 3.5a (see http://www.comsol.com/products/news/3.5 ), and it is used as the default meshing method for subdomains. It is possible to try another method, for example "free triangle", which was the default in 3.4. You would do this by passing the parameter-values 'Methodsub','tri' to the meshinit function:

fem.mesh = meshinit(fem,'Methodsub','tri')

Type 'help meshinit' at the Matlab command line for more info. I am not sure how to do this in the graphical user interface.

I found this first in another message posted here: http://tech.groups.yahoo.com/group/COMSOL_Users/message/7991 . Here it is discussed how you can use a try-catch block in matlab to choose the triangular method is the advancing front fails.
