Hello everyone:
I'm new to comsol and I have some questions as follows:
I have a model for force calculation of nanorod structure by the Maxwell stress tensor.
I use the expression as "emw.dnTx" to calculate the force (x component) . but the result is terrible.
firstly, I don't know the explicit definition of the expression"emw.dnTx". I just get the expression from a friend in the forum. But I don't know how to use it correctly.
Who can give me some refferences or relevant information? Thanks!
secondly, anyone has the similar model or the suggestion?
My model has been attached.
In the results-> derive value, I choose a surface and integrate it. The expression is "emw.dnTx"
