ParameterHandler: MultipleSelection of couples

[Franco Milicchio]

Dear all,

I am using the ParameterHandler class to select multiple parameters and lists, but I don't know if I could have something like the following.

What I'd like is to specify multiple parameters that, sort of nested, have a string and an integer. As a concrete example, I want to specify stress components, or strain, or others. For instance, I'd like to allow "stress", "strain", "work", and "power", but only the first two should have an additional integer. Take for instance the following (don't mind the syntax, please):

subsection dump

    set paraview = strain 1, work, stress 8

end

Is there any way I could achieve this with predefined classes? Or should I just read a list of strings and parse them myself?

Thanks!

Hi

In a similar case I have used this function

http://www.dealii.org/developer/doxygen/deal.II/namespaceUtilities.html#a8d799bb35ac16d206818c88e82afbfae

You can use this twice to get the result you want, combined with

http://www.dealii.org/developer/doxygen/deal.II/namespaceUtilities.html#af501c72fdc02dd969cd9d82d0f30642c

Best

Thanks, Praveen. 

I could use those, and in my tests that I've done now they work great, but this means I won't be able to detect errors automatically. This deal.II feature is the best thing, dropping it would be not so cool.

If not possible, I will just do this by hand.

Thank you!
