Problem in equation based modeling using axisymmetric components of Comsol Multiphysics?

10 October 2019 1 7K Report

Once one try to solve over the axisymmetric components, has to add extra source term inside the equation based modeling of Comsol Multiphysics. I want to know if this is still true in newer version of Comsol i.e., 5.4.

I believe you still have to be careful, if you are not using in-built functionality, such as the PDE module, where it is up to you to ensure that gradients are properly calculated: https://www.comsol.dk/blogs/guidelines-for-equation-based-modeling-in-axisymmetric-components/

How to make "time step to store output" variable in Comsol Multiphysics?

In time dependent study one can define the range like (0,0.1,1) the solver stores solution at each 0.1 interval. One can also define steps like range(0,0.1,0.9),range(0.9,0.01,1) it changes steps...
