    Hi,

    Does anyone know how to delete a simulation and its results using the Python API?

    Thanks!

        Hi Lj,

        the commands below should help:

        import s4l_v1.document as document
        sim = document.AllSimulations[0]    # access by index, starting with 0
        #sim = document.AllSimulations["my_simulation"]    # access by name
        
        sim.ClearResults()  # delete results
        
        sim.ResetVoxels()  # delete voxels
        
        document.AllSimulations.Remove(sim)   # remove simulation from project

            you're welcome!

            I would also recommend using the auto-completion feature in the Console. For example, if you type

            sim=document.AllSimulations[0]
            

            to assign the sim variable and then sim followed by a . (dot) , you should see all the functions that you can use with this simulation object. Usually easier than trying to remember all of them :)

              Yeah, I do use it. Its very helpful! I guess the mistake I was making was trying to find the delete/ remove within sim rather than document.allsimulations.

                yes, that one is not very obvious indeed. A hint might be given by looking at how simulations are "added" to the project (see for example the auto-generated code when you select a simulation and click "To-Python").

                    sim.ClearResults() # delete results
                    sim.ResetVoxels() # delete voxels
                    document.AllSimulations.Remove(sim) # remove simulation from project

                    after adding this lines i got this error :

                        can you provide a bit more detail about what you're trying to do?

                          i load several meshes one of them is moving and also each time it transmit other frequency, so for each state i need different simulation (sweep not good for me)

                            Hmm I am not sure I understand. Is it possible to share more of your code and explain exactly what is not working?

                            I use the lines of code you posted regularly and it works just fine.
