Use the numerical node to perform numerical evaluation from within the COMSOL Multiphysics model. Numerical operations such as computing averages, integrations, maxima, or minima of a given expression are available. You can also perform point and global evaluations.
where numtype is the type of operation to be performed by the node.
where <tabletag> is the tag of the table where you want to store the data evaluated with the numerical operations defined with the tag
<numtag>.
where <idx> is the column index of the table
<tabletag>.
