[aspect-devel] Using of multicomponent

Hi Liu,

In what sense does your result not look like you thought it would?  Was there an error?

You can think of each compositional field representing ‘a distinct’ material (or 'rock type').  In other words, each compositional has unique properties assigned by the user in the ‘multicomponent’ material model.  Does this make sense?

‘Component’ (i.e. from multicomponent) just means that there are multiple distinct domains that have unique material properties.  Each ‘component’ is assigned those properties based on a specific compositional field.  One compositional field is to tied to ‘each’ component if you will.

Cheers,
John

Multicomponent seems help.But the result does not like what I thought it would be.Here are my files .Any advice would be welcomed.

Thanks in advance.
