Combine Load Case

[harikrushna171]

I want to combine static and response spectrum results. For the first load combination, I use +1 and +1, and for the second load combination, -1 and +1.

1. Is the code mentioned below the correct approach?
2. How can I multiply the first load case by -1?

`# Displacement results
results_static = static_model.results
displacements_static = results_static.displacement()
fields_static_container = displacements_static.outputs.fields_container()

results_rs = response_model.results
displacements_rs = results_rs.displacement()
fields_rs_container = displacements_rs.outputs.fields_container()

op = dpf.operators.math.add_fc() # operator instantiation
op.inputs.fields_container1.connect(fields_static_container)
op.inputs.fields_container2.connect(fields_rs_container)
my_fields_container = op.outputs.fields_container()
static_model.metadata.meshed_region.plot(my_fields_container)`
