[aspect-devel] 3 composition/instability drip

[Payman Janbakhsh]

Hi John
I got it working without any error. Right now the lithosphere start to look strange when I add even one adaptive refinement. I'll keep working on it .
Thanks again
Payman

Hi Payman,

Thanks for sending this over.  To further assist, can you point to a specific model setup/publication this is based on (if it is based on one?). Also, can you send over an image of your initial compositional field?

The solver is not happy about something and it might be easier to diagnose with a few images.  I should have time later today or tomorrow morning to take a close look.  Currently playing catchup after traveling.

Cheers,
John

Good morning John
I have attached the prm and error files. I'm using version 1.5.
Hope you can point out the issue.
Many thanks

Hi Payman,

I'm guessing the "scheming_empty.prm" model refers to the Scheling et al 2008 (Phys. Earth. Planet Inter.) subduction benchchmark?

To help diagnose the problem, can you send over the .prm you used and a file with the error messages you received.  If the input file is from 2014, a few things may have changed in ASPECT, but it is good to hear the model still runs.

Also, what version of ASPECT are you currently using (version 1.4, master branch from github, etc).

Material model - I think one the existing models should be able to accommodate the parameters used in the Schmeling et al. 2008 paper, especially the linear viscous case?

Cheers,
John

Hi everyone,
I'm fairly new to ASPECT and trying to create an instability drip or a subduction model similar to what was used in scheming_empty.prm file in CIDER 2014.
I have mantle, lithosphere and crust each with their own density and viscosity.
I tried just to set up the parameter file with multicomponent material model without the use of a plugin but get errors related to convergence. Not sure if is doable without a plug in! let me know if so.
the virtualbox tutorial for CIDER 2014 which contained the related files is no longer available on wiki except the GeoMod2014 tutorial iv pdf file.
Unfortunately I'm stuck in creating the material model plug-in from the appropriate .cc and .h files.
Would you be able to direct me to the right resources so I can get this model running?

Thank you in advance

Payman
