    <p>There is not enough information given to be of much help.</p>
    <p>If its failing on one of the .struct files, you might take the
      problematic .struct from the elastic directory and create a new
      calculation directory for it (renaming the .struct to the new
      calculation directory's name).  Then, you could run that .struct
      through the initialize calc. steps (x nn, x sgroup, x symmetry,
      etc.) to analyze if there are any problems before or during x
      dstart with that particular .struct file.</p>
    <p>If it is caused by a program issue, there could be other messages
      that can help with troubleshooting the issue.  For example, if you
      used the gfortran compiler, there might be a Fortran runtime error
      and/or Backtrace like in the past post at [1].  If using the Intel
      compiler, it could be a forrtl traceback message like seen in the
      post at [2].  If you didn't use the recommended compiler settings
      in siteconfig but your own optimized and tailored settings, it
      could be that compiler options are missing for getting the
      traceback messages.  For the Intel compiler, for example, there is
      the <span class="kwd">-traceback option that is needed [3].<br>
      </span></p>

            Thank you very much for your answer and interest. I
            installed the latest version of Wien2k on my computer. I
            performed the base case calculations of the material I was
            working on. When I wanted to perform elastic calculations, I
            received the following error "dstart crashed!".<br>
