The archives for Version 3.2 contain one main directory named LSTASC_3.2, populated with its files. You can verify the contents of any archive that you download for Linux using the 'tar' command. For example,

      tar tvzf lstasc_32__x64_rhel6.tar.gz

The LS-TaSC User Manual is a PDF format file User_Manual.pdf.

To install, first 'cd' to a directory where you would like to maintain the LS-TaSC directory LSTASC_3.x as a subdirectory. Copy the downloaded archive into that directory. Then unpack the archive. A subdirectory LSTASC_3.x will be created beneath the chosen directory, in which all executables are placed. For example,

      cp lstasc_32_100691_x64_rhel6.tar.gz $HOME
      cd $HOME
      tar xvzf lstasc_32_100691_x64_rhel6.tar.gz

It is probably best to add the newly-created LSTASC_3.x directory to your path, though this is not necessary. For example, in this case you would add $HOME/LSTASC_3.2 to your path. LS-TaSC can be run strictly from the command line, directly in a batch mode. The preferred method is to use the LS-TaSC graphical user interface, and the visualization tools which are a part of this program.

      lstasc_script input.lstasc  (runs lstasc in batch mode)
      lstasc [input.lstasc]       (starts the graphical user interface tool)

NOTE: All of the files in the LSTASC_EXE must remain together in a directory with the exception of the example problems. The lstasc program will not function correctly if it cannot find the lstasc_script and other executables.

2. Installation under Microsoft Windows

First download the zipped archive for your machine.


AMD/Intel Windows 64-bit LS-TaSC3.2-win-x64-installer20170124.exe


AMD/Intel Windows 64-bit LS-Tasc3.1-win-x64-installer20160608.exe

The archive for LS-TaSC 3 is an installation program. Save the file to disk before running.

NOTE: All of the files in the LSTASC_EXE must remain together in a directory with the exception of the example problems. The lstasc program will not function correctly if it cannot find the lstasc_script and other executables.

Manual Examples: There is a zipfile containing the examples used in the manual. You should unpack this archive. For more about extracting and running these examples, read the next section.

3. Manual Examples

There is an archive of Examples contained in manual_examples.tar. The Windows installation file contains manual_examples.zipinstead. The zip file is unpacked in the usual way under Microsoft Windows. You may unpack the tar archive under Linux using the tar command

      tar xvf manual_examples.tar

The files in this archive are contained in one main directory named MANUAL. All example input.lstasc files have an name with a suffix '.lstasc'.

  • To run an example under Linux: issue the command 'lstasc input_filename.lstasc', and enter the 'Run' panel. Or, start 'lstasc' with no command line arguments, and then browse for the input file.
  • To run an example under Microsoft Windows: Start the lstasc program and then open the file from the File menu. Switch to the Run tab in order to start the program.

*** NOTE *** All problems require some solver in order to run. Typically the solver must be located in the PATH or in the LSTASC_EXE directory. Open the Cases tab, and double click on the items to view the solver command that is required. A typical problem requires an executable lsdyna_double in the PATH, or in the LSTASC_EXE directory.
