In order:<\/p>\n<ul>\n<li>model is modified accordingly to the parameter variation (see below for available drivers);<\/li>\n<li>the loadcase specified in the mask is run. If you need to run a combination, transform it into a loadcase with the corresponding command in <em>Assign\/Analysis settings<\/em><\/li>\n<li>selected elements are checked upon built-in checks (for steeel, aluminium, concrete, etc., according to available licenses) or using custom scripts containing user&#8217;s criteria placed in &#8220;verification&#8221; folder (see Chapter 4.3 of <a href=\"https:\/\/www.nextfem.it\/webManuals\/en\/\" target=\"_blank\" rel=\"noopener\">Users&#8217; manual<\/a>)<\/li>\n<li>check results are enveloped, resulting in a scalar representing the outcome.This value is plotted against the iteration number in the graph at the bottom.<\/li>\n<\/ul>\n<p>There are several pre-defined criteria for running the parametric analysis, such as:<\/p>\n<ol>\n<li><strong>Change Section criterion<\/strong>: it allows to change the section of the selected elements. Transversal sections are taken from library (fully customizable, as described in Chapter 4.2 of <a href=\"https:\/\/www.nextfem.it\/webManuals\/en\/\" target=\"_blank\" rel=\"noopener\">Users&#8217; manual<\/a>). Specify the search pattern in the <em>Filter<\/em> column by using wildcards such as * (sequence of any character) or ? (replacement for a single character).<br \/>\nE.g. the filter <em>HE*B<\/em> will select all the sections named as the pattern specifies: HE 100 B, HE 120 B, etc.<\/li>\n<li><strong>Change Material criterion<\/strong>: it allows to change the material of the selected elements. Materials are selected amongst the ones in library, which is fully customizable (see Chapter 4.1 of <a href=\"https:\/\/www.nextfem.it\/webManuals\/en\/\" target=\"_blank\" rel=\"noopener\">Users&#8217; manual<\/a>). Specify the search pattern in the <em>Filter<\/em> column by using wildcards such as * (sequence of any character) or ? (replacement for a single character).<br \/>\nE.g. the filter <em>S???<\/em> will select all the materials named as the pattern specifies: S235, S275, etc.<\/li>\n<li><strong>Move Node criterion<\/strong>: this permits to move the specified node by the distances defined in global coordinates for the desired times. To move more than one node, use a group name, previously defined in <em>View\/Select group<\/em> command. The input line should be: <em>node,numIters,incrX,incrY,incrZ<\/em>. First increment is always performed with a null vector.<br \/>\nE.g. for a single node increasing 1m along X for 10 times: <em>2,10,1,0,0<\/em> .<br \/>\nTo move a node group use: <em>grp:GroupName,10,1,0,0<\/em> .<\/li>\n<li><strong>Change load criterion<\/strong>: it allows to change the load in a single node or element. Only uniform loads are supported. The input line should be: <em>n\/e,node\/element ID,numIncr,loadIncr,loadcase<\/em>.<br \/>\nE.g. for a point load on node 2 increasing 10 times for 2.5kN in loadcase <em>perm<\/em>, use: n,2,10,2.5,perm .<\/li>\n<li><strong>Change factor criterion<\/strong>: it allows to change the factor of the function associated to the selected loadcase. The input line should be: <em>numIncr,factIncrementPerc,loadcase<\/em><br \/>\nE.g. 10,0.1,perm .<\/li>\n<\/ol>\n<p>Finally, each row in the table specifies a parameter. Each parameter can be run as <strong>independent<\/strong> (the single parameter is varied in a single analysis) or as <strong>dependent<\/strong> (the single parameter in combined with any other dependent parameter specified). In the latter case, the number of iterations generated can be high.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Parametric analysis run parametric analyses AND checking with ease The plugin for parametric analysis represents the last frontier of structural optimization of civil structures.
