Dear all.
I have a question: in the latest ASPECT version is it possible to combine Visco Plastic and Melt Global models? If yes, I appreciate some tips.
Thanks.
Vlad
@vladycm - In theory you can use the compositing material model (search for “compositing” in this manual section) to combine any two material models, but whether that will give the desired outcome is another question.
Can you provide more information on what you hope to achieve by combining the Visco Plastic and Melt Global material models?
If you want to combine a nonlinear solid rheology model (e.g., Visco Plastic or Grain Size) with two-phase melting, using the Reactive Fluid Transport material model (see documentation page above) might be a more straightforward path.
This model enables combining (compositing) different solid material models with different fluid transport (darcy vs two-phase) and reaction schemes.
Please let us know how we can help further and what details you can provide regarding your project goals.

Dear John.
Thank you for your reply. I want to use the cookbook_extension_model.prm and add a thermal anomaly and incorporate melting.
I will have a look at the Reactive Fluid Transport material model.

Hi @vladycm ,
Thank you for your reply. I want to use the cookbook_extension_model.prm and add a thermal anomaly and incorporate melting.
One colleague is doing exactly this with the reactive fluid transport model. They are still working through debugging a few issues that occur under specific parts of the parameter space, but the hope is to add a cookbook soon highlighting this functionality. I’ll enquire about the anticipated timeline.
In the shorter term, going through the existing tests and benchmarks that use the reactive fluid transport model is a great start. There are a few tests case that specifically focus on melting.

Dear John.
This is indeed good news, I this such a cookbook model will have many interesting applications. Meantime I will have a look over the reactive fluid transport model.
Best.
