A reader to extract LS-DYNA results

Project description

LS-Reader Project

The LS-Reader is designed to read LS-DYNA results and can extract the data of more than 2000 such as stress, strain, id, history variable, effective plastic strain, number of elements, binout data and so on now. The LS-Reader provides an uniform interface for getting these data. For convenience, input parameters, like number of state, number of integration point, are designed as keyword arguments. More details please see LS-Reader Tutorial.

How to use

# D3plotReader
from lsreader import D3plotReader, DataType as dt

data_path = your/d3plot/file/path
dr = D3plotReader(data_path)

shell_stress = dr.get_data(dt.D3P_SHELL_STRESS, ist=0, ipt=1)

shell_eps = dr.get_data(dt.D3P_SHELL_EFFECTIVE_PLASTIC_STRAIN, ist=0, ipt=1)

thickness = dr.get_data(dt.D3P_SHELL_THICKNESS, ist=11)

num_solid_element = dr.get_data(dt.D3P_NUM_SOLID)

# Get d3plot data by part
num_solid_pid_4 = dr.get_data(dt.D3P_NUM_SOLID, ipart_user=4)

shell_stress_pid_4 = dr.get_data(dt.D3P_SHELL_STRESS, ist=4, ipt=0, ipart_user=4)

# Get data by part set
num_shells = dr.get_data(dt.D3P_NUM_SHELL, ipartset_user=[1, 2])

# Get numpy array(numpy is required to be installed, using "pip install numpy")
shell_stress = dr.get_data(dt.D3P_SHELL_STRESS, ist=0, ipt=1, ask_for_numpy_array=True)

# BinoutReader
from lsreader import BinoutReader, BINOUT_DataType as bdt

data_path = your/binout/file/path
br = BinoutReader(data_path)

branches = br.get_data(bdt.BINOUT_BRANCHES)

ids = br.get_data(bdt.BINOUT_NODOUT_IDS)
