From robert.klofkorn at math.lu.se Thu May 30 18:39:18 2024 From: robert.klofkorn at math.lu.se (=?utf-8?B?Um9iZXJ0IEtsw7Zma29ybg==?=) Date: Thu, 30 May 2024 16:39:18 +0000 Subject: [dune-fem] Change of solver parameters. In-Reply-To: References: Message-ID: Dear dune-fem community, recently we merge a change of solver parameter names to the main branch of dune-fem. The reasons is the implementation of linearized schemes which should not be configured with parameters starting the keyword 'newton.'. This mainly entails the change from 'newton' to 'nonlinear' in solver parameters for schemes, e.g. Galerkin scheme. Furthermore, the linear solver inside the nonlinear solver is now steered by just 'linear.xxx', i.e. just remove the 'newton.' in front of those parameters. The parameter 'newton.linear.tolerance.strategy' has been renamed to 'nonlinear.forcing'. A proper deprecation has been implemented which means once you updated to a newer version of dune-fem, your code will still work. Some warnings will be printed in this case to explain how to transition to the new of solver configuration. If for some reason your code breaks, you can revert back to the state from May 29, 2024 or earlier. You can also pip install dune-fem==2.10.dev20240529 which contains the state just before the merge. If you do encounter problems please contact the development team immediately. With regards, Robert -------------- next part -------------- A non-text attachment was scrubbed...
