How to make cross product in comsol

Please login with a confirmed email address before reporting spam

Hi, I'm a beginner COMSOL user and i need some help for the simulation I'm making. I need to compute a body torque (which I still do not know where to find it in COMSOL) which is the result of a cross product between a first vector that follows the structure during its deformation and another one (an external field) which remains constant in its direction during the deformation. How can I define this body torque and how can I compute the cross product when one vector changes its direction during the simulation?

thank you!

I often have to create cross-products in RF simulations. Assuming you can get to the components of the vectors to be multiplied, then it's just a matter of writing out the math for each component of the resulting cross-product. https://en.wikipedia.org/wiki/Cross_product
