<p>Individual nodes and elements are changed during the optimization. Thus,
the commands used in <span class = "ph">Abaqus</span>
to define nodes and elements of transformations are invalid. The appearance
of these options in the finite element input file leads to a termination
of the optimization. Therefore, these definitions should be executed
in a preprocessor such that an explicit definition of the nodes and elements
is created.</p>
<p>When input files already exist, then a data check should be carried
out with <span class = "ph">Abaqus</span>.
In this data check, the nodes and elements are generated and written in
the output file (*.dat). The node and element definitions can then be
copied from the output file and inserted into a new input file.</p>

</pre>
<p>Parametric inputs in the <span class = "ph">Abaqus</span>
input file cannot be used with <span class = "ph">Tosca Structure</span>.
A parameter check should be executed when parametric inputs exist. This
parameter check causes an evaluation and substitution of only the parametric
inputs:</p>
<pre class = "codeblock">
<code class = "ph codeph">
abaqus job=job-name parametercheck
</code>
</pre>
<p>Then a modified input file containing no parameter and parameter dependence
table definitions and &lt;parameter&gt; instances is produced. Use the
generated file named <code class = "ph codeph">job-name.pes</code> for optimization
with <span class = "ph">Tosca Structure</span>.
