How can I obtain Nodal Forces at selected nodes/elements/areas for all time steps in a transient analysis?

[bedermaus]

I can get nodal reaction forces from results for whole load steap. But how i can get reaction forces just for defined area in format:

SubStep LoadStep Time TotalReactionForce
1       1        0.5          ....
2       1        1             ....

I tried with dpf-core like:

from ansys.dpf import core as dpf
.....
.....
self.result = mapdl.result  # Geting result
self.result_file = mapdl._result_file
def MaxResults(self, container):
        scoping = dpf.Scoping()
        scoping.ids = range(1, int(self.sub_step_spinbox.value()) + 1)
        container.inputs.time_scoping.connect(scoping)
        fc = container.outputs.fields_container()
        #tfq = fc.time_freq_support
        #time_field = tfq.frequencies
        normOp = dpf.Operator("norm_fc")
        minmaxOp = dpf.Operator("min_max_fc")
        normOp.inputs.fields_container.connect(fc)
        minmaxOp.inputs.connect(normOp.outputs)
        fieldMax = minmaxOp.outputs.field_max()
        return fieldMax.data
model = dpf.Model(self.result_file)
force_reaction = model.results.force()
print(self.MaxResults(force_reaction))

But getting wrong results
Any ideas?

Hi @bedermaus, since you are using DPF I would recommend you to open an issue in their repo: https://github.com/pyansys/pydpf-core/issues
