Hi all,
I’m trying to use “compositing” Material model to use the melting parameterization of the “melt simple” model with a more realistic viscosity model that provided by the “visco plastic” model.
I set like this:
subsection Compositing
set Viscosity = visco plastic
set Compressibility = melt simple
set Density = melt simple
set Entropy derivative pressure = melt simple
set Entropy derivative temperature = melt simple
set Reaction terms = melt simple
set Specific heat = melt simple
set Thermal conductivity = melt simple
set Thermal expansion coefficient = melt simple
end
However, I got this error:
An error occurred in line <1500> of file </home/ASPECT/bin/aspect/source/simulator/melt.cc> in function
** void aspect::MeltHandler::add_current_constraints(dealii::AffineConstraints&) [with int dim = 2]**
The violated condition was: **
** Plugins::plugin_type_matches<const MaterialModel::MeltInterface>(this->get_material_model())
Additional information: **
** Your material model does not derive from MaterialModel::MeltInterface,
** which is required.**
How can I achieve the combination of melting parameterization and elastic-plastic deformation of the material? Or can it be?
Many thanks!
Best wishes,
Judy
