[CIG-LONG] Subduction models & Underworld

[Louis Moresi]

Weinan,

(I am cc’ing the list in case anybody has a similar enquiry).

Although Gale has not been used a lot for subduction modeling, it is worth noting that it was a fork of the Underworld code which is used extensively for
subduction modelling. Underworld is supported and under active development (though not as a CIG project) and subduction continues to be a focus of the researchers using it. Underworld2 addresses many of the usability issues associated with Underworld and Gale and may be worth a look.

As John points out, this is very dependent on your specific problem but you can see www.underworldcode.org<http://www.underworldcode.org> for details or the underworldcode Facebook page.
Underworld is particularly suited to looking at continental deformation in response to mantle / lithosphere forcing. The setting of Luzon is quite a challenge for modeling, though, and no one approach is likely to be a silver-bullet

Hi Weinan,

Gale has been used to model subduction, but it’s application really depends on what specific processes you want to look at.

Also, do note that while Gale is still available for download, it fall under the "not supported and not under development” category.

There is a reason for that and very few (if any) groups in the long-term tectonics community are still using it.

Will numerical modeling be a key component of your thesis?  If not, I strongly suggest reaching out to collaborate with individuals who have worked on modeling subduction processes that are within your range of interests.

Hope this helps.

Cheers,

                    > Hello,
                    > I am a Ph.D student who is on the geological research about the region of the Philippines. First of all, I appreciate the development of the softwares to improve the study on the tectonics, especially for the geologists who are not so good at coding and finite element analysis, just like me.

                    > I am intending to do some simulations about the tectonic evolution on Luzon Island using the Gale. As we know, the Luzon Island is in the middle of the two subduction zones, Manila and East Luzon subduction zones, and it is very rare all over the world. But I meet a problem in the simulation, so I want to know whether the Gale can solve the tectonic modeling of three units, like the Luzon. If Gale can, can you give me a example so that I can understand and do the simulation further?
