Hi Jason, the problem with your approach is the following: the read_input - function reads the whole parameter file and calls for each of the parameters given in the form "set parameter_name = value" the scan_line - function and checks, if this parameter was being declared, if this is not the case, an exception is thrown.
The simplest way is to declare all entries first, read the parameters from the file and after this, you can do what you want. If the parameters are in the file, you know them and you can declare them, this should not be a problem, or is there something I do not get? Maybe this helps, Best, Martin ----- Original Message ----- From: Jason Sheldon To: [email protected] Sent: Monday, August 29, 2011 7:49 PM Subject: [deal.II] Issue with parameter handlers Hello everyone, I've come across the need to read specific values from a parameter file before I know which values I will be reading later. I can get the code to compile and run, but it shoots out a lot of warnings saying parameters have not been declared. I've mocked up a small example of this. (attached) I was wondering if there was a way to prevent these warnings from occurring, or a different way I should be calling the parameter file to avoid the issue. -- -Jason Sheldon ------------------------------------------------------------------------------ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
