Remote Computing is an innovative method within Autodesk® Simulation CFD to run analyses on remote computers on your network. It is a way to temporarily ramp up analysis capability by using (often under-utilized) in-house computer resources. Remote Computing is not an ASP model nor is it distributed computing. Alternatively, it is an innovative way to run multiple analyses on multiple computers.
Interface Computer
The simulation is defined on the interface computer. The CAD model is usually prepared here as well.
Solver Computer
The simulation is run on the solver computer. Use the Solver Computers dialog (Setup > Simulation drop down menu > Solver Computers) to designate computers on the network as remote solver computers.
Server Manager
SimCFDServerManager.exe is a service that must be running on each Solver computer. This service waits for a call from an interface computer to start an analysis. When a call is received, it provides communication between the two computers.
This service is configured to start automatically on the Interface and Solver computers when the software is installed. It can be stopped, started, and monitored using SimCFDServerManager.exe, located in the installation directory.
If an error occurs on the Interface computer indicating a refused connection, check that this service is running on the Solver computer.
The Interface and Solver computer(s) must be connected on the same network.
Interface Computer
A valid Autodesk® Simulation CFD license is required on the Interface computer.
Use the Solver Computers dialog (Setup > Simulation expansion panel > Solver Computers) to add computers as Solver Computers. Specify the following for each computer:
Solver computers are listed in the Solver Computer menu on the Control tab of the Solve dialog.
Solver Computer
Launch the model from the CAD system to the Interface computer, and set up the simulation as you would a model to be run locally. When ready to run, open the Solve dialog, and select the desired computer from the Solver Computer menu on the Control tab. Click Solve to launch the simulation.
Instead of running on the local computer, the simulation data is sent to the specified Solver Computer. The mesh is generated and the results are calculated. As the scenario runs, graphical results are sent back to the Interface computer for run-time results visualization.
While running, the design study can be closed and Autodesk® Simulation CFD shut down on the Interface machine. When the design study is opened again, the current progress or the finished results are automatically sent from the Solver computer.
To view the status of scenarios running on the Solver Computers, open the Solution Monitor. Use this to check machine availability and analysis status.

A Network (floating) license is required to use Remote Computing.
On a VPN, performance may be degraded due to slow network performance. The communication may even be interrupted due to network time out.
Performance may be degraded if the interface and analysis computers are not on the same sub-net.
When launching from Pro/Engineer with the Mechanica option, the meshing must be performed on the Interface Computer before the model is run on a Solver computer.
