version 4.3a
the equation in COMSOL is like:
lambda^2*ea*U-lambda*da*U+......
however, in my equation, there is lambda not in the first two items in the above equation, for example, there is also lambda in the C, Alpha and so on.
how can i use the lambda in other items?
I've triey write lambda directly but got an err, should i use it as fem.lambda or eigen.lambda or else?
