Moving car example by combining Speos files#

This tutorial demonstrates how to run moving car workflow use case. ## Prerequisites

Perform imports#

[1]:
import os
from pathlib import Path

from ansys.speos.core import Part, Speos
from ansys.speos.core.sensor import SensorCamera
from ansys.speos.core.simulation import SimulationInverse
from ansys.speos.core.source import SourceLuminaire
from ansys.speos.core.workflow.combine_speos import SpeosFileInstance, combine_speos

Define constants#

Constants help ensure consistency and avoid repetition throughout the example.

[2]:
HOSTNAME = "localhost"
GRPC_PORT = 50098  # Be sure the Speos GRPC Server has been started on this port.
CAR_NAMES = ["BlueCar", "RedCar"]
ENVIRONMENT_NAME = "Env_Simplified"
USE_DOCKER = True  # Set to False if you're running this example locally as a Notebook.
USE_GPU = False

Coordinate systems#

Define the global coordinate systems for each of the assets.

[3]:
GLOBAL_CS = [
    0,  # Origin x
    0,  # Origin y
    0,  # Origin z
    1,  # x-direction x
    0,  # x-direction y
    0,  # x-direction z
    0,  # y-direction x
    1,  # y-direction y
    0,  # y-direction z
    0,  # z-direction x
    0,  # z-direction y
    1,  # z-direction z
]
CAR_CS = {
    "red": [-4000, 0, 48000, 1.0, 0.0, 0.0, 0.0, 0.0, -1.0, 0.0, 1.0, 0.0],
    "blue": [2000, 0, 35000, 0.0, 0.0, -1.0, -1.0, 0.0, 0.0, 0.0, 1.0, 0.0],
}

Load assets#

Assets used to run this example are available in the PySpeos repository on GitHub.

Note: Make sure you have downloaded simulation assets and set assets_data_path to point to the assets folder.

[4]:
if USE_DOCKER:  # Running on the remote server.
    assets_data_path = Path("/app") / "assets"
else:
    assets_data_path = Path("/path/to/your/download/assets/directory")

Create connection with speos rpc server#

[5]:
speos = Speos(host=HOSTNAME, port=GRPC_PORT)

Combine several speos files into one project#

Here we are building a project with:

  • An environment which is a road

  • A blue car

  • A red car

[6]:
full_env_path = assets_data_path / f"{ENVIRONMENT_NAME}.speos" / f"{ENVIRONMENT_NAME}.speos"
car_paths = [assets_data_path / f"{car}.speos" / f"{car}.speos" for car in CAR_NAMES]
assets = [
    SpeosFileInstance(
        speos_file=str(full_env_path),
        axis_system=GLOBAL_CS,
    ),
    SpeosFileInstance(
        speos_file=str(car_paths[0]),
        axis_system=CAR_CS["red"],
    ),
    SpeosFileInstance(
        speos_file=str(car_paths[1]),
        axis_system=CAR_CS["blue"],
    ),
]
p = combine_speos(
    speos=speos,
    speos_to_combine=assets,
)
[7]:
print(p)

Preview the project#

User can review the created/loaded project using preview method.

Complete the project with sensor/source/simulation#

We are adding a camera sensor to have output results, a luminaire to have a light source.

And, we gather the source and the sensor into a simulation (we will compute it just after).

Create a sensor#

Create a source#

In this example, a luminaire source is created with an IES file.

Modify part#

Move the part via changing the axis_system of a part.

axis_system is a list of 12 float values: x, y, z, x_vect_x, x_vect_y, x_vect_z, y_vect_x, y_vect_y, y_vect_z, z_vect_x, z_vect_y, z_vect_z.
