Hello everbody,

 

 I am trying to run a simulation with a dimerized spin Hamiltonian with nn interactions and an additional nnn interaction. I tried to invoke this by definin a model J1J2delta within my library. Unfortunately, when I try to run the simulation in the command line, I recieve the error description:

 

"J1J2delta model not implemented in file factory.C"

 

What do I have to do then? I have taken the library from the standard installation of apls and solely added the J1J"model, stored it (I can visualize it in the explorer), but somehow the program does not seem to know, what to do woth it....

 

Kindest thamks in advance,

 

Alex
