<body class='hmmessage'><div dir='ltr'>I have a small question about the use of PC field split, does it expect variables to be arranged in a particular fashion? Should it be variable major (all degrees of freedom corresponding to the first followed by all degrees of freedom corresponding to the next) or node major ( all degrees of freedom corresponding to each node - with a sub block structure . Is there some way of switching between the two ?<div>Thanks, <br>Subramanya Sadasiva </div> </div></body>
