How to open result (MS Windows OS only)#
This tutorial demonstrates how to open and review results using workflow method.
Prerequisites#
Perform imports#
[1]:
import os
from pathlib import Path
from ansys.speos.core import Project, Speos
from ansys.speos.core.simulation import SimulationDirect
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.
FILE_NAME = "LG_50M_Colorimetric_short.sv5"
RESULT_NAME = "ASSEMBLY1.DS (0).Dom Irradiance Sensor (0).xmp"
USE_DOCKER = True # Set to False if you're running this example locally as a Notebook.
USE_GPU = False
Model Setup#
Load assets#
The 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_pathto point to the assets folder.
[3]:
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")
Connect to the RPC Server#
This Python client connects to a server where the Speos engine is running as a service. In this example, the server and client are the same machine.
[4]:
speos = Speos(host=HOSTNAME, port=GRPC_PORT)
Create project from a Speos file#
The Project class is instantiated by passing a Speos instance and the name of the Speos project file.
[5]:
p = Project(
speos=speos,
path=str(assets_data_path / FILE_NAME / FILE_NAME),
)
print(p)
