  • Erroneous exception for certain boundary periodifications.

Changes from 3.0.3 to 3.0.4

• Bug fixes JCMgeo: - Geometric primitive “MultiLayer” caused JCMgeo to crash when intersecting with the computational domain boundary.

Changes from 3.0.2 to 3.0.3

• New features

  • New geometric primitive “MultiLayer” to ease for example Bragg mirror definition.
  • Support for point sources (dipoles) in cylindrically symmetric geometries.

• Bug fixes JCMsolve:

  • Wrong results for Fourier transform in cylindrically symmetric geometries.
