Probably something like: [K_UU K_UV K_UW] [U] [K_VU K_VV K_VW] [V] [K_WU K_WV K_WW] [W] but it sounds like you are getting ready to do something ill-advised, such as indexing directly into the solution vector based on and assumed variable ordering. Use the DofMap for this... -J > Thanks a lot. > > Regards, > Yujie ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
