Question about import external data in cylindrical coordinate system?

Please login with a confirmed email address before reporting spam

Hi all,

My geometry is a cylinder and I intend to import external heat source data to it.

The external data table in .csv file has 4 columns, for example: r(cm) fai(rad) z(cm) power(w/cm3) 1 -3.14 0 10 2 +3.14 1 20 ......

Maybe I have to import the data in cylindrical coordinate system of comsol, therefore my problems are : 1) how to set cylindrical coordinate in comsol? 2) the problem of heat source formular unit : int1(x[1/cm], y[????], z[1/cm]) [W/cm^3]

I tried y[1/rad] in comsol default coordiate system, but the color is always orange, maybe y[1/rad] is only valid in cylindrical coordinate?

Any help will be appreciated and thanks in advance!

Zhefu
