What's this

OOMMF-MEL includes the magnetoelastic (MEL) energy terms in micromagnetic simulations with Object-Oriented Micromagnetic Framework (OOMMF). To handle spatially-nonuniform, time-varying strain, the following three Oxs_Ext classes are provided.

  • YY_FixedMEL

  • Calculates the MEL energy and effective field with constant strain.

  • YY_StageMEL

  • Updates the strain at each stage.

  • YY_TransformStageMEL

  • Applies time-dependent linear transform to the stage-specific strain to provide more flexibility.

Installation

Download code

You need a working OOMMF (recommended 1.2a5 or higher) and building environment. See OOMMF documentation. Copy .cc and .h files into the directory (OOMMF_DIR)/app/oxs/local/ and (re-)build OOMMF by typing tclsh oommf.tcl pimake in your OOMMF root directory.
