  • shell_layer (int, optional) – If merge_solid_shell pin set to true, user have to choose a shell layer. for shell/solid mixed field, gather in one field all solids and shells (only on one layer).

Returns:

field

Return type:

inputs

Return type:

InputsToNodal

property outputs#

Examples

Compute the minimum of displacement by chaining the "U" and "min_max_fc" operators.

>>> from ansys.dpf import core as dpf
>>> from ansys.dpf.core import examples
>>> data_src = dpf.DataSources(examples.find_multishells_rst())

>>> max_fc_op = dpf.operators.min_max.min_max_fc()
>>> max_fc_op.inputs.connect(disp_op.outputs)
