I'm working in solid mechanics. I've a variational form of a system, (PFA variational form.jpg)
pi is funtional
sigma bar = effective stress
epsilon bar dot =effective strain rater
epsilon dot v = volmetric strain rate
lamda = lagrange multiplier
F is the traction vecotor
v is the test function

but it doesn't have a test function in any of the domain terms . then how can I write this in expression under 'weak expressions' of comsol. ?
