      <p class="para_division">Predict sheet metal splitting during the draw process.</p>
      <div class="title_division">Purpose</div>
      <p class="para_division">The purpose of this check is to ensure that splitting does not&nbsp; occur when there is no restraint at the boundary (the holding condition = free). Splitting under this condition indicates that it will be almost impossible to form the part using the assigned material in a single draw operation.</p>
      <div class="title_division">Computational Method</div>
      <p class="para_division">The AutoFormTM OneStep solver is used to analyze the formability of the part. The AutoForm OneStep run is a Part Only simulation and preparation of the data for input, launching the simulation, and retrieval of the results is completely automatic.</p>
      <p class="para_division">The results are presented as shown:</p>
      <p class="para_division"><img align="bottom" src="graphics/dfm_split_examp.gif" border="0"></p>
      <p class="para_division">Analysis of the results of the simulation is done by classifying each element using a Forming Limit Diagram (FLD). For a complete description of the Application of the FLD, see  </p>
