Installation Instructions

Installing the Simulation Moldflow Insight - Solvers HOTFIX DL20323299 in a Linux environment involves several steps.

  1. Before installing software

    To prevent problems during the installation of Autodesk Simulation Moldflow Insight, there are initial tasks that should be performed.

    • Perform a system backup

      Before you install the Autodesk Simulation Moldflow Insight – Solvers application, you or a system administrator should do a full system backup.

    • Stop all running jobs

      From a client machine, stop all currently running analysis jobs using the Job Manager feature Analysis > Job Manager.

      This ensures no “File in use” errors occur during installation.

    • Check if Autodesk Simulation Moldflow Insight solvers have been installed previously

      Open the file /var/adm/moldflow/installations and if ami2013 appears in that file, you will need to uninstall the existing version of Autodesk Simulation Moldflow Insight 2013 before proceeding.

    • Uninstall any previous Autodesk Simulation Moldflow Insight 2013 release

      Log in as the user on the machine where the Autodesk Simulation Moldflow Insight - Solvers application has been installed previously.

      Ensure that no Autodesk jobs are running currently on the machine using the client-server functionality of the Job Manager.

      The uninstall script will automatically stop the Job Manager on the current machine, which would cause any jobs currently running to abort.

        a) Log in as root, and run the script bin/mfuninstall in the directory that was specified for the ami2013 release in the /var/adm/moldflow/installations file (for example: ./mfuninstall)

        b) Follow the prompt [enter y] to uninstall the AMI 2013 solvers.

        c) Change to the parent directory in which the Autodesk Simulation Moldflow Insight - Solvers application is installed (for example, /opt/Autodesk/moldflow), and delete the ami2013 directory and subdirectories below it (for example: rm -r ami2013.)

  2. Preparing to install by downloading tar files

    You must be logged in as root to install the Autodesk Simulation Moldflow Insight – HOTFIX DL20323299 software. Use the following command to ensure that you are using the root environment:

    su -

    • Create the directory /opt/Autodesk/moldflow/install. This directory will be used to temporarily hold files during the installation.

      mkdir -p /opt/Autodesk/moldflow/install

      NOTE: This path is case sensitive. The capital A in Autodesk is recommended.

      · Copy the install tar file [ami_full_eng_lanthanum_main_12343_001_lx26ol.tar] into the /opt/Autodesk/moldflow/install directory.

      · Change to the /opt/Autodesk/moldflow/install directory.

      · Extract the files setup.exe and setup.inf from the <downloaded tar file> using the following command.

      tar xvof <downloaded tar file> setup.exe setup.inf

      The extraction process may take several minutes to complete.

      · Run the setup.exe script in the install directory:

      ./setup.exe

    Now continue to follow the instructions detailed in the section Installing the Autodesk Simulation Moldflow Insight – HOTFIX DL20323299 application on Linux systems.

  3. Network installation

    Many customers choose to install the Autodesk Simulation Moldflow Insight software on one machine (the file server) and then run the solvers on other machines in the network (the client machines) via an NFS mounted disk. If you wish to install the Autodesk Simulation Moldflow Insight software on a file server, and then set up the client machines, you will launch the Autodesk Simulation Moldflow Insight installation script in a different manner than if you are installing on the local machine. Specific instructions for this step are included in Setting up client machines from a file server on page 4.

  4. Installing the Autodesk Simulation Moldflow Insight – HOTFIX DL20323299 application on Linux systems

    Once the Autodesk Simulation Moldflow installation script has started, you need to:

    • Enter 1 to SELECT ALL PRODUCTS and press Enter.
    • Enter 4 to INSTALL SELECTED PRODUCTS and press Enter.
    • Choose whether you are installing from a CD-ROM.
    • If you enter y, then you must enter the name of the tar file corresponding to the platform that you wish to use
    • If you enter n, you will be prompted to enter the path and name of the tar file (ami_full_eng_lanthanum_main_12343_001_lx26ol.tar). Press Enter.

    The installation script will now load and extract the files. This may take a while depending on the speed of your machine and DVD-ROM drive if you are installing from a DVD.

    • Choose whether you want to install the Autodesk client machine setup.

    NOTE: The Autodesk client machine will install the Autodesk Job Manager on the client machine, allow you to set your temporary directory location, and set values for a selection of environment variables.

    • If you enter y, you will launch the Autodesk client machine setup script now.

    Continue to complete the remaining steps to install

    • If you enter n, you will launch the client setup script manually at a later time. You will be returned to the Autodesk Moldflow Insight Setup Installation Menu and you do not have to complete the remaining steps to install Autodesk Simulation Moldflow Insight – Solvers HOTFIX DL20323299.

    NOTE: To run the client setup script at a later time, enter:

    /opt/Autodesk/moldflow/ami2013/bin/mfclient

    • Select the location of a temporary files directory.

    This is where the Job Manager will write temporary files whenever an analysis is run on the current machine. For optimum performance, it is essential that you select a local drive rather than a network drive. The amount of temporary space that will be required depends primarily on the size and complexity of the models being analyzed, the number of simulations being run simultaneously, and the frequency with which simulations are launched. You should select a temporary directory providing several gigabytes of disk space as a minimum.

    NOTE: The /tmp directory on many Linux systems will not have sufficient space for use as the Job Manager temporary directory. Please check the available disk space carefully.

    • Enter y to confirm the default location of the temporary directory (/tmp), or enter n to specify an alternate directory.

    NOTE: You can change the location of the Job Manager temporary directory at any time. To do so, log in as root on the client machine, and stop the Job Manager ( ./ami2013jmrc stop in the /var/adm/moldflow/ directory). Edit the MFSYN_TMP variable in the ami2013jm_perhost_vars.ksh file found in the /var/adm/moldflow/ directory. Restart the Job Manager (./ami2013jmrc start in the /var/adm/moldflow/ directory).

    If you selected an alternative directory, the script will display the available disk space in the specified directory and ask for confirmation before proceeding.

    When the setup script has restarted the Job Manager, your Autodesk client machine setup for Autodesk Simulation Moldflow Insight – Solvers is complete.

  5. Setting up client machines from a file server

    If you have installed the required software components on a file server, and you wish to set up other Autodesk client machines, you will need to follow the steps below to mount the directory on the file server where the Autodesk Simulation Moldflow Insight server has been installed, and then start the mfclient script manually on each machine that is to act as an Autodesk client.

    NOTE: If you have installed the software locally, you can still use this machine as an Autodesk file server for other same-platform machines in your network. That is, you can always mount the file system and configure other Autodesk client machines, regardless of how the Autodesk file server has been configured.

    • To mount the installation directory and manually launch the mfclient script, you must log in as root on the client machine.
    • Mount the directory <servername>:/opt/Autodesk/moldflow/ami2013 on the current machine.

    For example, for a file server with hostname hawk and software installed in /opt/Autodesk/moldflow/ami2013, you would enter the command:

    mount hawk:/opt/Autodesk/moldflow/ami2013

    NOTE: The directory path where the software is mounted must be the same on all same-platform Autodesk client machines. This is because the settings in the MFENV.csh or MFENV.sh file include the path.

    • Start the mfclient script by changing to the directory

      /opt/Autodesk/moldflow/ami2013/bin and typing ./mfclient

    • The mfclient script prompts you to confirm whether you wish to proceed: Do you wish to proceed with the Autodesk Client Machine setup? (y/n) [yes]:
    • Enter y to continue.

    The script will now check for the required operating system components and patches and configure the relevant Autodesk Simulation Moldflow Insight Solver HOTFIX DL20323299 related script files.

    If you wish to run the Autodesk Simulation Moldflow Insight solvers from the command line rather than via the Job Manager, you will need to setup each user's environment.

  6. Setting up each user's environment

    Each Autodesk Simulation Moldflow Insight user's environment must include PATH and other environment variables that enable Autodesk Simulation Moldflow Insight to function correctly.

    NOTE: Setting up an environment should be done by the user. This will ensure correct ownership and permissions for the altered files.

  7. C-shell user environment setup
    • Open the user's .cshrc file in their home directory in a text editor.
    • If present, remove any previous release Autodesk Simulation Moldflow
  8. Insight or Dynamic Series environment variable settings.
    • Add the following line to the bottom of the file:

      source /opt/Autodesk/moldflow/ami2013/data/MFENV.csh

    • Save the changes to the .cshrc file and exit the editor.
    • Source the .cshrc file by entering:
      source .cshrc

    Bourne-shell and Korn-shell user environment setup

    • Open the user's .profile file in their home directory in a text editor.
    • If present, remove any Autodesk Simulation Moldflow environment variable settings for a previous Autodesk Simulation Moldflow Insightor Dynamic Series release.
    • Add the following line to the bottom of the file:

      /opt/Autodesk/moldflow/ami2013/data/MFENV.sh

    NOTE: The dot and space character ( . ) at the start of the line are essential. The dot is actually a shell command similar to the C-shell source command.

    • Save the changes to the .profile file and exit the editor.
    • Source the .profile file by entering:

      . ./.profile
