Hello,

I am working on a piezoelectric model of the main domain (quartz) and I want to add another material (Aluminume), but this message appears to me, I need help what is wrong have done "Undefined variable. - Variable: comp1.solid.epsilonrmZX - Geometry: geom1 - Domain: 2 Failed to evaluate Jacobian of expression. - Expression: dvol(comp1.es.DZcomp1.es.d) Failed to evaluate Jacobian of expression. - Expression: ((comp1.es.DXtest(comp1.es.EX)+comp1.es.DYtest(comp1.es.EY)+comp1.es.DZtest(comp1.es.EZ))comp1.es.d)*(dvol)"

Aluminum must be modeled (selected) as a linear elastic material.

Quartz is complicated. Good luck.
