Hi Patricia,<br><br>check sfepy.mechanics.tensors.transform_data(). You will need to prepare the transformation matrices for the spheroid yourself - take inspiration in prepare_cylindrical_transform() in the same module .<br><br>r.<br><br><div id="htc_header" style="">----- Reply message -----<br>From: &quot;Patricia Garcia Cañadilla&quot; &lt;patricia.ga...@gmail.com&gt;<br>To: &lt;sfep...@googlegroups.com&gt;<br>Subject: [sfepy-devel] Transform coordinates stress tensor<br>Date: Wed, May 27, 2015 13:06<br><br></div><br><div dir="ltr">Hi all,<div><br></div><div>I have a 3D ellipsoid and I will need to transform the stress tensor (9 components) from cartesian to cylindrical / prolate spheroid coordinates.
