I need to declare a non-uniform volume charge distribution within a certain geometry. I tried declaring a function as a function of R or Rho without success. The function is accepted by the software (e.g. 10*R nC/m^3), however, when I plot the Qsurf I noticed a uniform distribution instead of a non-uniform.

Hello,

Ensure that the charge density function is correctly specified and normalized. The cartesian coordinate system (XYZ) is the basis for defining the charge density as a function of position, and the cylindrical and spherical coordinate system may not work. Also, consider checking in quantities other than Qsurf.
