[deal.II] Where to get Adol-C?

2018-05-14 Thread 'Maxi Miller' via deal.II User Group
Hei, I would like to include Adol-C in my deal.II-library. Now deal.II needs at least the version 2.6.4 from adol-c, but on the current web page to this project (https://projects.coin-or.org/ADOL-C) the newest version is 2.6.3. Thus I was wondering how I could obtain a newer version to use with

Feimi, There is no substitute for this function. The reason it was deprecated is because we are trying to get a unified minimal interface for all our vector classes. The idea is to make it easy to switch between different vector classes. In the process, we have deprecated functions that were no

Hi Bruno, Thanks for the reply! I got the idea. I will try to write my own loop to realize this function. Thanks! Feimi On Monday, May 14, 2018 at 8:47:34 AM UTC-4, Bruno Turcksin wrote: > > Feimi, > > There is no substitute for this function. The reason it was deprecated is > because we are t

Hi Wolfgang, Thank you for the detailed explanation! Actually what I want to do is to evaluate the inverse of a lumped diagonal matrix to mimic the matrix inverse. Anyway, I will write my own loop to avoid using ratio(). Thanks again! Feimi On Monday, May 14, 2018 at 10:23:12 AM UTC-4, Wolfgan

Dear Prof. Arndt, actually, I hope that Dealii can include (adaptive) isogeometric analysis element in future (e.g. high order phase-field problems solidification, grain growth,... ) Warm regards, Yaakov On Monday, May 7, 2018 at 5:06:54 PM UTC+2, Daniel Arndt wrote: > > Yaakov, > > Mixed form
