Shearing box in SPH#

This simple example shows how to run an unstratified shearing box simulaiton

 9 import shamrock
10
11 # If we use the shamrock executable to run this script instead of the python interpreter,
12 # we should not initialize the system as the shamrock executable needs to handle specific MPI logic
13 if not shamrock.sys.is_initialized():
14     shamrock.change_loglevel(1)
15     shamrock.sys.init("0:0")
-> modified loglevel to 0 enabled log types :
log status :
 - Loglevel: 1, enabled log types :
[xxx] Info: xxx ( logger::info )
[xxx] : xxx ( logger::normal )
[xxx] Warning: xxx ( logger::warn )
[xxx] Error: xxx ( logger::err )

Initialize context & attach a SPH model to it

21 ctx = shamrock.Context()
22 ctx.pdata_layout_new()
23
24 model = shamrock.get_Model_SPH(context=ctx, vector_type="f64_3", sph_kernel="M4")

56 # Create the dump directory if it does not exist
57 if shamrock.sys.world_rank() == 0:
58     os.makedirs(dump_folder, exist_ok=True)

Generate the config & init the scheduler
