gRPC connection
gRPC is the framework that enables the communication between Python and the Oasys LS-DYNA Environment programs.
If a Python script starts an instance of a Oasys LS-DYNA Environment program, for example PRIMER, Python will connect to the program automatically.
But for a Python script to connect to an already running instance of a program, the program must be in a special mode telling it to listen on a port for gRPC messages. There are two possible methods to do so:
Use the -grpc command line argument when starting the program, e.g:
Bash (Unix Shell)C:\\path_to_your_executable\\primerXX_x64.exe' -grpc=50051
Start the program in the usual way, and then under Options > gRPC/Python click on "Start":
Note: 50051 is the default gRPC port for PRIMER, but a different port can be used.
In an analogous mode gRPC can be started for D3PLOT and T/HIS (the default port numbers are 50054 and 50052 respectively).
For REPORTER the start gRPC panel is under Script > gRPC/Python (the default port number is 50053):
