Is it possible to expand a field to a bigger scoping?

Thomas25

Hi people,

I am trying to expand a field with only 1 value on one node from the min_max operator. To the same scoping of FieldA.

def ones_like(field):
    """Creates a field with values 1 scoped over the original field"""
    zeros = scale(field, 0.0)
    ones = ops.math.add_constant(zeros, 1.0)
    return ones.outputs.getfield()

def scale(field, factor):
    op = ops.math.scale()
    op.inputs.field.Connect(field)
    op.inputs.weights.Connect(factor)
    return op.outputs.getfield()

min_max_op = ops.min_max.min_max()
min_max_op.inputs.field.Connect(FieldA)
Field_min = min_max_op.outputs.getfield_min()
Field_scaled = scale(ones_like(FieldA), Field_min)

Does someone know how to make a field with only 1 value and the right scoping?
Or how to convert a field to a scalar?

Kind Regards,

Hello People.

I have found something that works:

min_max_op = ops.min_max.min_max()

min_max_op.inputs.field.Connect(FieldA)

Field_min = min_max_op.outputs.getfield_min()

Field_list = Field_min.Data

minimum = Field_list[0]


Field_scaled = scale(ones_like(FieldA), minimum)

.Data on a field creates a list of that field. The min_max operator creates a field with only one value so getting the first item from the list will be a float of the minimum value.

Using my ones_like and scale functions from the meassage above. I can create a field with just that minimum value across a new scoping of FieldA.
