Hi all,
<div><br>
</div>
<div>For my PhD project I am working on modelling subduction with Aspect. I would like to start with a simple linear viscous subduction benchmark including eight materials. The materials all have different densities and different viscosities. As far as I understand,
with material model "Simple model" it is possible to define eight compositional fields, but not to give them
<i>all</i> different densities and/or viscosities. In the input file one can set "<span class="Apple-style-span" style="font-family: CMR8; ">Density differential for compositional field 1" and the Composition viscosity prefactor, but then they apply to all
fields; you cannot specify them for each field individually.</span></div>
<div><span class="Apple-style-span" style="font-family: CMR8; "><br>
</span></div>
<div><font class="Apple-style-span" face="CMR8">Can you tell me whether my understanding is correct, and if so, whether you intend to make it possible to define multiple compositional fields coupled to different densities/viscosities from the input file? I
would guess the alternative is to hardwire the materials into the material model myself.</font></div>
<div><font class="Apple-style-span" face="CMR8"><br>
</font></div>
<div><font class="Apple-style-span" face="CMR8">Thank you so much for your help,</font></div>
