Re: [deal.II] Re: Relationships between material parameters

Another idea: create a struct ElasticProperties that can be constructed using different functions (maybe with functions like make_from_mu_and_nu()) and that has member functions to compute arbitrary output. Internally it would convert to one representation during construction. On Tue, Jan 10, 2017

Hi Wolfgang, Do you have any recommendations on a function hierarchy/naming scheme? Most of these functions will take two numbers and return another one, which means that most of them have the same argument list. In my own code I have nested namespaces and functions like double Constitutive_Par

[deal.II] Re: Library file sizes

Praveen, yes it's normal. The debug library needs to keep a list of symbols that can be used by the debugger (if you use the release version in a debugger, you won't get much information). There may also partly due to the optimization of the code. Best, Bruno On Tuesday, January 10, 2017 at

Dear Seyed, There is a table in wikipedia that details how to convert between fundamental elastic material parameters. Due to the number of permutations that are available, I would be hesitant to add this to deal.II itself. However,

[deal.II] Relationships between material parameters

Hi everyone, I am just implementing some material parameter relationships such as lambda = E * v / (1 + v) / (1 - 2 * v) for instance. There is a table for such conversion of quantities. Would it be beneficial to have such a library that computes and converts these quantities automatically
