Dymola model execution

You can perform a co-simulation between an Abaqus/Standard or Abaqus/Explicit model and a model exported from Dymola. This procedure requires that you have the following two files available in your current working directory: dymosim.dll, which contains the Dymola export of your model details, and libdsdll.dll, which contains a basic collection of Dymola libraries. See Structural-to-logical co-simulation for details on creating or obtaining these files.

The following topics are discussed:

Command line options

input

This option is used to specify the map file name. The map file has a .sgn file extension.

port

This option is used to specify the TCP/UDP port number for co-simulation between solvers using the direct coupling interface, which includes co-simulation between Abaqus and certain third-party analysis programs. Set port equal to the port number used for the connection. The default value is 48000. The default port number that Abaqus uses to initiate communication can be set with the cosimulation_port parameter in the environment file (see Environment File Settings). This option is used in conjunction with the host option. For more information, see Selecting TCP/UDP port numbers.

host

This option is used to specify the host name for co-simulation between solvers using the direct coupling interface, which includes co-simulation between Abaqus and certain third-party analysis programs. This option specifies the name of the machine that is hosting the connection. Refer to the third-party program documentation to determine if the host option is required. This option is used in conjunction with the port option.

Examples

The following example illustrates use of the Dymola execution procedure in a co-simulation involving Abaqus/Explicit and an exported Dymola model.

Running the Dymola simulation

Use the following command to start the Dymola simulation, which will listen on port 44444 for a connection from Abaqus/Explicit: 

abaqus dymola input=inverted_pend_map port=44444

Running the Abaqus/Explicit simulation

Use the following command for the Abaqus/Explicit analysis, which will connect to the Dymola simulation on machine “mecury,” via port 44444: 

abaqus job=inverted_pend_xpl host=mercury
port=44444
