You mean that the temperature is given ? Could you write down the expression of the term which takes into account the thermal expansion (I am not a specialist). If it is a supplementary term in the equation compared to the standard linearize elasticity, it should be possible to build a brick which modify the linearized elasticity brick adding a term in the stiffness matrix. -- Yves. ------------------------------------------------------------------------- Yves Renard ([EMAIL PROTECTED]) tel : (33) 04.72.43.80.11 Pole de Mathematiques, INSA de Lyon fax : (33) 04.72.43.85.29 Institut Camille Jordan - CNRS UMR 5208 20, rue Albert Einstein 69621 Villeurbanne Cedex, FRANCE http://math.univ-lyon1.fr/~renard ------------------------------------------------------------------------- _______________________________________________ Getfem-users mailing list [email protected] https://mail.gna.org/listinfo/getfem-users
