3. MODEL GEOMETRY

3.1 Changing a model generated via the parametric templates:

    If some of the original, parametrically generated, nodes 
    are moved using the single node move option, ACES deletes 
    the original, (selected), nodes and creates new nodes at 
    the new positions.  Once the original nodes are deleted, 
    the moving load keys on either side of those nodes cannot 
    take part in the vehicle load distribution process. Hence 
    any axles that land on members lying between those nodes 
    will not be taken into consideration when the loading is 
    generated.    
 
    The current solution is to either use a denser original 
    mesh when creating the model or to use the  <Move a 
    rectangular (or fenced) block of nodes>  because these 
    two move options do not delete the original nodes.
    Please contact AAS for further support.

5. FINITE ELEMENTS

5.1 Shear in triangular elements:

    Problems may sometimes occurs when calculating shear in
    triangular elements.  Generally this occurs when the
    local element axis points directly at a node.  When this
    happens the calculation of the shears may become invalid.
    The work-around is to calculate the shears from the
    reactions.  Please contact AAS for further support.

7.1 Moving Nodes in the Model

    If  some of the original, parametrically generated, nodes
    are moved using the single node move option ACES deletes 
    the original, selected, nodes and creates new nodes at 
    the new positions.  Once the original nodes are deleted, 
    the moving load keys on either side of those nodes cannot 
    take part in the vehicle load distribution process. Hence 
    any axles that land on members lying between those nodes 
    will not be taken into consideration when the loading is 
    generated.    
 
    The current solution is to either use a denser original 
    mesh when creating the model or to use the  <Move a 
    rectangular (or fenced) block of nodes>  because these 
    two move options do not delete the original nodes.

10.  CONTINUOUS BEAM MODULE (CBM)

10.1 Persistent activation of the install wizard

     If the system displays an error message indicating that
     the CBM module is not available or if it launches an
     installation dialog you will need to perform the 
     following procedure:

       - Cancel the process and exit from ACES
       - Rerun ACES and select the CBM module
       - Open the Windows Task Manager
       - Click on the "Processes" tab
       - Locate the file called “msiexec.exe”  
       - End the process (via a button at bottom right)
       - The CBM module should work properly.

     If the problem persits you may have to repeat the
     above steps.  Please contact AAS for further support.
