<HTML><BODY>Hi, Neks!<br><br>I am working with a complex geometry and want to change positions of some points in spectral elements. I've read in documentation that i,j,k,e in xm1(i,j,k,e), for example, are changed from 1 to nx1,ny1,nz1 and nelv respectively. But during my tests it's seemed that in different elements x,y,z axis not always correspond to the global coordinate system. Am I right?<br><br>And how could I change only the lowest slice of an element, for example?<br><br>Best regards,<br>Elizabeth</BODY></HTML>
