Delete Simulation and Results

[LJ]

Hi,

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

Thanks!

Why use Python api

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

[LJ]

Thank you @Sylvain!

Thank you @Sylvain!

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 :)

[LJ]

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.

[Sylvain]

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").

[LJ]

That makes sense- thank you!

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

after adding this lines i got this error :

[michaelsch]

also h5 output files disappear !

[LJ]

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

[michaelsch]

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)

[LJ]

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.
