<div class="textblock"><p>In this tutorial, you will learn to use the Expression-assembler of G+Smo, see <a class="el" href="classgismo_1_1gsExprAssembler.html">gsExprAssembler</a>. This powerful tool can be used to assemble a system of equations, given the expressions of a weak formulation.</p>
<h1><a class="anchor" id="files"></a>
Relevant source files</h1>
<p>The files relevant for using the <a class="el" href="classgismo_1_1gsExprAssembler.html">gsExprAssembler</a> are the following:</p>
<ul>
<li><code><a class="el" href="gsExprAssembler_8h.html" title="Generic expressions matrix assembly. ">gsExprAssembler.h</a></code> : contains the assembly routines for generic expressions; all performed with the <a class="el" href="classgismo_1_1gsExprAssembler.html">gsExprAssembler</a>,</li>
<li><code><a class="el" href="gsExprEvaluator_8h.html" title="Generic expressions evaluator. ">gsExprEvaluator.h</a></code> : contains the class that is used to evaluate expressions; <a class="el" href="classgismo_1_1gsExprEvaluator.html">gsExprEvaluator</a>,</li>
<li><code><a class="el" href="gsAssemblerOptions_8h.html" title="Provides assembler and solver options. ">gsAssemblerOptions.h</a></code> : contains the <a class="el" href="structgismo_1_1gsAssemblerOptions.html">gsAssemblerOptions</a> class which is used to define options for the Expression-assembler,</li>
<li><code><a class="el" href="gsExpressions_8h.html" title="Defines different expressions. ">gsExpressions.h</a></code> : contains classes that are the actual expressions and the arithmetic to evaluate them,</li>
<li><code><a class="el" href="gsExprHelper_8h.html" title="Generic expressions helper. ">gsExprHelper.h</a></code> : contains the <a class="el" href="classgismo_1_1gsExprHelper.html">gsExprHelper</a> class to store evaluation data of expression-related objects,</li>
<li><code><a class="el" href="gsDirichletValues_8h.html" title="The functions compute Dirichlet degrees of freedom using various methods. ">gsDirichletValues.h</a></code> : contains classes to evaluate non-homogeneous Dirichlet boundary conditions defined for a space.</li>
</ul>
<p>From those classes the top three (<a class="el" href="classgismo_1_1gsExprAssembler.html">gsExprAssembler</a>, <a class="el" href="classgismo_1_1gsExprEvaluator.html">gsExprEvaluator</a> and <a class="el" href="structgismo_1_1gsAssemblerOptions.html">gsAssemblerOptions</a>) are the ones that are actually called in your code, wheres the other ones are used under the hood.</p>
<p>Furthermore, for any boundary value problem boundary conditions are to be defined. This happens with the <a class="el" href="classgismo_1_1gsBoundaryConditions.html">gsBoundaryConditions</a> class.</p>
