calculator

property Variables.calculator: ens_calculator

The calculator interface presents a Pythonic mechanism to access all the EnSight calculator functions: Calculator Functions.

Unlike the native API function pyensight.ensight_api.variables.evaluate() and the object API function pyensight.ens_globals.ENS_GLOBALS.create_variable() which take a string as the function definition, the methods on the calculator object take natural Python objects and return any newly created ENS_VARIABLE object.

Returns:

ens_calculator

An object supporting a method for each EnSight calculator function.

Examples

The following are equavalent:

>>> # Native API
>>> session.ensight.part.select_all()
>>> session.ensight.variables.evaluate("EleSize = EleSize(plist)")
>>> var1 = session.ensight.objs.core.VARIABLES["EleSize"][0]
>>> session.ensight.variables.evaluate("OffsetVar = OffsetVar(plist,Momentum,2e-05)")
>>> var2 = session.ensight.objs.core.VARIABLES["OffsetVar"][0]
>>> # Object API
>>> parts = session.ensight.objs.core.PARTS
>>> var1 = session.ensight.objs.core.create_variable("EleSize", "EleSize(plist)", sources=parts)
>>> var2 = session.ensight.objs.core.create_variable("OffsetVar", "OffsetVar(plist,Momentum,2e-05)", sources=parts)
>>> # ens_calculator API
>>> parts = session.ensight.objs.core.PARTS
>>> var1 = session.ensight.utils.variables.calculator.elesize(parts, output_varname="EleSize")
>>> momentum = session.objs.core.PARTS["Momentum"]
>>> var2 = session.ensight.utils.variables.calculator.offsetvar(parts, momentum[0], 2.e-5, output_varname="OffsetVar")
