Dear Michael, The classes that better serve your purpose are the Tensor and SymmetricTensor classes: https://dealii.org/current/doxygen/deal.II/classTensor.html https://dealii.org/current/doxygen/deal.II/classSymmetricTensor.html

Hi Bruno, Thanks for the link. The thing is, I am using a virtual box machine with Deal.II and Ubuntu. where should I get Eclipse installed? I guess doing it in windows should not work. Thanks for your time. Martin On Wednesday, 21 July 2021 at 10:11:01 pm UTC+10 bruno.t...@gmail.com

Hi David, Thanks for the detailed explanation. I suppose below procedure should work: 1 Open Deal.II example, the cpp file, with text editor 2 make changes to it, and save it as another cpp file 3 Use cMake to run this new cpp file at the command line 4 if no mistake, the new cpp file will

[deal.II] Matrix Multiplication

Dear dealii users, I want to construct a matrix [image: E=1/2(F^TF-1)]. My approach is as follows. FullMatrix F(3,3) = 0.0; // deformation gradient FullMatrix E(3,3) = 0.0; // Green strain FullMatrix I (IdentityMatrix(3)); F.Tmmult(E, F); E.add(-1, I); E.add(2, E); I wonder if there is an more

Hi all, I've used the #include command in a program in order to use UMFPack. I'm able to compile and run everything fine in Debug mode (provided by Eclipse via the cmake4eclipse add-on). However, when I try to switch to Release mode to optimize the program, it gives me the following warning:

Re: [deal.II] Deal.II programming environment

Hi Martin, No, that's a very good question - it's important to set up a good development environment. You CAN use plain text editors and run CMake from the command line (in fact, with many tools you will end up still running CMake from a window inside them) but its usually better to use

Martin, You can use whatever you like, there is no such thing as a typical environment. With that being said, we do have documentation and videos to help you setup Eclipse. See https://github.com/dealii/dealii/wiki/Eclipse https://www.math.colostate.edu/~bangerth/videos.676.7.html
