How do I retrieve NMISC results for APDL hydrostatic elements (HSFLD242) with DPF?

You can use the following code.

Note

1. This code uses all the HSFLD242 elements in the named selection "HFL". As HSFLD242 are created by the solver, one needs to create APDL component name "HFL" using APDL Snippet (not via Mechanical).

2. This code uses time-scoping for 4 time-steps, please adjust as per your model.

import mech_dpf
 
mech_dpf.setExtAPI(ExtAPI)
import Ans.DataProcessing as dpf
 
dpf.DataProcessingCore.LoadLibrary("math", r"C:\Program Files\ANSYS Inc\v211\aisol\bin\winx64\Ans.Dpf.Math.dll")
ds = mech_dpf.GetDataSources(0)
 
time_freq = dpf.operators.metadata.time_freq_provider()
time_freq.inputs.data_sources.Connect(ds)
 
hfl_elements = dpf.Operator("scoping_provider_by_ns")
hfl_elements.Connect(0, "Elemental")
hfl_elements.Connect(1, "HFL")
hfl_elements.Connect(4, ds)
 
# Time Scoping
time_scoping = dpf.data.Scoping()
time_scoping.Ids = [1, 2, 3, 4]
 
# Density NMISC1
density = dpf.Operator("mapdl::nmisc")
density.Connect(0, time_scoping)
density.Connect(1, hfl_elements.GetOutputAsScoping(0))
density.Connect(4, ds)
# Please use the NMISC number as a second argument here
density.Connect(10, 1)
 
# TVOL NMISC3
tvol = dpf.Operator("mapdl::nmisc")
tvol.Connect(0, time_scoping)
tvol.Connect(1, hfl_elements.GetOutputAsScoping(0))
tvol.Connect(4, ds)
# Please use the NMISC number as a second argument here
tvol.Connect(10, 3)
 
# Density Results for 1st time step
print density.GetOutputAsFieldsContainer(0)[0].Data
 
# TVOL Results for 4th time step
print tvol.GetOutputAsFieldsContainer(0)[3].Data
