Creates an ISession object that represents the specified AIMMS model, using the default configuration.

public static ISession openSession(string aimmsLocation, string projectLocation);

Creates an ISession object that represents the specified AIMMS model, using a user-specified configuration.

public static ISession openSession(string aimmsLocation, string projectLocation, IConfig sessionConfig);

The specified AIMMS model runs in a separate process. 

For the format of the location URI you can either specify the local folder name (see examples) where AIMMS is installed, or use a URI as discussed in Running a remote session to start a remote AIMMS session. 

As second argument, you need an AIMMS project file (*.prj), if you have an AIMMS pack (*.aimmspack), unpack it first. 

When the session cannot be created, an exception is thrown, describing what went wrong. Common causes are:

• Incorrect path for AIMMS installation specified;
• Project filename cannot be opened (especially when running remotely);
• The remote server is configured incorrectly or not started.

Open session may timeout for different reasons:

• The ConnectTimeout determines the time it may take to setup the connection.
• The normal timeout determines the time further initialization steps may take, especially starting the AimmsModel may take some time.

Configure the timeout for opening the session by IConfig.ConnectTimeout.
