Log and Output Files for Troubleshooting

Description

A series of log files is written out with every Autodesk® Simulation CFD analysis that lists the all of the steps in the process and all of the communications between the different modules.  

Recall that Autodesk® Simulation CFD is built on a client-server structure. This means that it is broken into a number of modules that are managed by a Solver Manager. These modules communicate with one another through the Server Manager. Several of the log files record these communications, and can be useful for troubleshooting errors such as "Cannot connect to Solver," "Unable to Start Solver," and "Did not receive reply from remote host." 

These log files contain a lot of information, and their meaning may be unclear for some users. They can be helpful, however, for our technical support team and developers when diagnosing problems. 

Several of the log files record error messages that have occurred in their respective module. These can be very useful for troubleshooting problems in a specific phase of the analysis process.  

The following is a brief description of the log files and their locations.

Location: analysis name_logs folder (a sub-folder of the working directory)

analysis name_model.log: Lists steps of geometry import and any errors that occurred during the import process when lauching from a Parasolid or Acis-based CAD system. This is a good file to review if problems occur when launching. 

analysis name_mesh.log: Record of steps that occur during mesh generation. This is a good file to review if there are problems when meshing. 

analysis name_solver.log: Lists the communications and actions performed before, during, and after an analysis by the Solver. 

analysis name_mesher.log: Lists the communications and actions performed during mesh generation by the Mesher. 

analysis name_client.log: Lists the communications and actions performed before, during, and after an analysis.  

cfdesign.log: Lists the steps performed for license authentication, the communication, and analysis steps performed during an analysis.

Location: "Analyze" subfolder of the Simulation CFD installation folder

solver_manager.log: Lists the communications and actions performed by the Solve Manager. This is a good resource to check if problems occurred while running remotely or when queuing analyses.

Location: C:\Users\username\AppData\Local\Autodesk\Simulation CFD 2012

mesher.log: this is written when the analysis model is created from a Parasolid or Acis geometry file

meshsimLaunch.log: this is written when the analysis model is created from a Pro/Engineer or CATIA model 

meshsim.log: this contains the steps of the meshing process 

cfdesign.log: this is the same as the cfdesign.log file contained in the logs subfolder of the working directory. 

solver_mgr_machinename.log: this is similar to the solver_manager.log file, but contains process steps for machines that are used for Fast Tracking an analysis. This can be useful for diagnosing problems with Remote solving.
