How to create a project#

This tutorial demonstrates how to create a project.

What is a project?#

A project is a speos simulation container that includes parts, material properties, sensor, sources and simulations.

In this tutorial you will learn how to create a project from scratch or from a pre-defined .speos file.

[1]:
import os
from pathlib import Path

from ansys.speos.core import Project, Speos
from ansys.speos.core.sensor import SensorIrradiance
from ansys.speos.core.simulation import SimulationDirect
from ansys.speos.core.source import SourceLuminaire, SourceSurface

# If using docker container
assets_data_path = Path("/app") / "assets"
# If using local server
# assets_data_path = Path().resolve().parent.parent / "tests" / "assets"
# If using a different path
# assets_data_path = Path("path/to/downloaded/example/assets")

Create connection with speos rpc server#

[2]:
speos = Speos(host="localhost", port=50098)

New empty project#

An empty project can be created by only passing speos rpc server to the Project class.

[3]:
p = Project(speos=speos)
print(p)
{
    "name": "",
    "description": "",
    "metadata": {},
    "part_guid": "",
    "sources": [],
    "sensors": [],
    "simulations": [],
    "materials": [],
    "scenes": []
}

create feature - e.g. source

[4]:
source1 = p.create_source(name="Source.1", feature_type=SourceLuminaire)
source1.set_intensity_file_uri(uri=str(assets_data_path / "IES_C_DETECTOR.ies"))
source1.commit()
[4]:
<ansys.speos.core.source.SourceLuminaire at 0x7f165a28aec0>

create feature - e.g. sensor

[5]:
sensor1 = p.create_sensor(name="Sensor.1")
sensor1.commit()
[5]:
<ansys.speos.core.sensor.SensorIrradiance at 0x7f165a28b1f0>

create feature - e.g. optical property

[6]:
opt_prop1 = p.create_optical_property(name="Material.1")
opt_prop1.commit()
[6]:
<ansys.speos.core.opt_prop.OptProp at 0x7f165a28ab00>

Read Project#

User can read the content of a project via simplily printing the project

[7]:
print(p)

Or, user can use the find_key method to read a specific feature:

[8]:
for it in p.find_key(key="monochromatic"):
    print(it)

Find a feature inside a project#

Use find method with an exact name#

If no feature is found, an empty list is returned.

[9]:
features = p.find(name="UnexistingName")
print(features)
[]
[10]:
features = p.find(name="Sensor.1")
print(features[0])
{
    "name": "Sensor.1",
    "metadata": {
        "UniqueId": "4840bd98-f196-465e-ada6-c9833fc15972"
    },

    "result_file_name": "",
    "sensor": {
        "irradiance_sensor_template": {
            "sensor_type_photometric": {},

                "y_end": 50.0,
                "y_sampling": 100
            },
            "axis_system": [
                0.0,
                0.0,
                0.0,
                1.0,
                0.0,

        },
        "name": "Sensor.1",
        "description": "",
        "metadata": {}
    }
}

Use find method with feature type#

Here a wrong type is given: no source is called Sensor.1 in the project

[11]:
features = p.find(name="Sensor.1", feature_type=SourceLuminaire)
print(features)
[]
[12]:
features = p.find(name="Sensor.1", feature_type=SensorIrradiance)
print(features[0])
{
    "name": "Sensor.1",
    "metadata": {

    "description": "",
    "result_file_name": "",
    "sensor": {

            "illuminance_type_planar": {},
            "dimensions": {

                "y_end": 50.0,
                "y_sampling": 100
            },
            "axis_system": [
                0.0,
                0.0,

                1.0,
                0.0,
                0.0,
                0.0,
                1.0,
                0.0,
                0.0,
                0.0,

            "layer_type_none": {},
            "ray_file_type": "RayFileNone",
            "integration_direction": []
        },
        "name": "Sensor.1",
        "description": "",
        "metadata": {}
    }
}

Use find method with approximation name with regex#

find a feature with name starting with Mat

[13]:
features = p.find(name="Mat.*", name_regex=True)
for feat in features:
    print(str(type(feat)) + " : name=" + feat._name)
<class 'ansys.speos.core.opt_prop.OptProp'> : name=Material.1

find all features without defining any name

[14]:
features = p.find(name=".*", name_regex=True)
for feat in features:
    print(str(type(feat)) + " : name=" + feat._name)
<class 'ansys.speos.core.source.SourceLuminaire'> : name=Source.1
<class 'ansys.speos.core.sensor.SensorIrradiance'> : name=Sensor.1
<class 'ansys.speos.core.opt_prop.OptProp'> : name=Material.1

Delete#

This erases the scene content in server database.

This deletes also each feature of the project

[15]:
p.delete()
print(p)
{
    "name": "",
    "description": "",
    "metadata": {},
    "part_guid": "",
    "sources": [],
    "sensors": [],
    "simulations": [],
    "materials": [],
    "scenes": []
}

As the features were deleted just above -> this returns an empty vector

[16]:
print(p.find(name="Sensor.1"))
[]

Create project from pre-defined speos project#

Via passing the .speos/.sv5 file path to the Project class.

[17]:
p2 = Project(
    speos=speos,
    path=str(assets_data_path / "LG_50M_Colorimetric_short.sv5" / "LG_50M_Colorimetric_short.sv5"),

Preview the part information#

User can check the project part using preview method.

[18]:
p2.preview()

use find_key method to find specific information

[19]:
for it in p2.find_key(key="surface"):
    print(it)
(".sources[.name='Dom Source 2 (0) in SOURCE2'].source.surface", {'radiant_flux': {'radiant_value': 6.590041607465698}, 'intensity_guid': 'ab30cd22-ca8c-4442-a803-4903dfb8f80d', 'exitance_constant': {'geo_paths': [{'geo_path': 'Solid Body in SOURCE2:2920204960/Face in SOURCE2:222', 'reverse_normal': False}]}, 'spectrum_guid': 'a68c90c6-5430-4530-9f10-8b6d02b9f3f7', 'intensity': {'cos': {'N': 1.0, 'total_angle': 180.0}, 'name': '', 'description': '', 'metadata': {}}, 'spectrum': {'library': {'file_uri': '/app/assets/LG_50M_Colorimetric_short.sv5/Red Spectrum.spectrum'}, 'name': '', 'description': '', 'metadata': {}}})

Use find method to retrieve feature:

e.g. surface source

[20]:
features = p2.find(name=".*", name_regex=True, feature_type=SourceSurface)
print(features)
for feat in features:
    print(str(type(feat)) + " : name=" + feat._name)
src = features[1]
[<ansys.speos.core.source.SourceSurface object at 0x7f165a2dfa30>, <ansys.speos.core.source.SourceSurface object at 0x7f165a2df790>]
<class 'ansys.speos.core.source.SourceSurface'> : name=Dom Source 2 (0) in SOURCE2
<class 'ansys.speos.core.source.SourceSurface'> : name=Surface Source (0) in SOURCE1

modify the surface source, e.g. surface source wavelength:

[21]:
src.set_spectrum().set_monochromatic(wavelength=550)
src.commit()
[21]:
<ansys.speos.core.source.SourceSurface at 0x7f165a2df790>
