Scalar Expansion

This is an example using the csdl expand operation in order to expand a scalar value into an array.

from csdl_om import Simulatorimport csdlfrom csdl import Modelimport numpy as np

class ExampleScalar2Array(Model):
    def define(self):        # Expanding a scalar into an array        scalar = self.declare_variable('scalar', val=1.)        expanded_scalar = csdl.expand(scalar, (2, 3))        self.register_output('expanded_scalar', expanded_scalar)

sim = Simulator(ExampleScalar2Array())sim.run()
print('scalar', sim['scalar'].shape)print(sim['scalar'])print('expanded_scalar', sim['expanded_scalar'].shape)print(sim['expanded_scalar'])

[1.]expanded_scalar (2, 3)[[1. 1. 1.] [1. 1. 1.]]
