COMSOL 4.2: How to use the calculated values of eigenfunctions u_i (calculated at step 1 of a given studio), in a next (step 2) of it?

04 April 2014 1 335 Report

In a first step I calculate the eigenfunctions u_i and eigenvalues e_i of a homogeneous second order differential equation.

In a second step I want to use the i-th eigenfunction squared (u_i)^2 as the density source in a Poisson equation.

Can anyone help me to do such calculation with COMSOL 4.2? Should I use time-dependent modal? If so, how to use it?

Sorry, I can not help you, just like computers only use the general equation of the sum.

That is enough to deduce the properties of the particles and also calculate

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

What techniques can I use to determine the miscibility of polymer blends?

The term miscibility refers to the single-phase state in thermodynamics. I do not mean the compatibility of different components. To determine the miscibility I know several techniques such as...
