Re: [deal.II] Step 44: imported 2d mesh fails to converge to solution

Jean-Paul, The boundary ID output from the four different calculations are as follows (before any boundary IDs are set to 6): 1) 3D, no imported mesh: equal numbers for boundary IDs 0, 1, 2, 3, 4, and 5. This calculation converges to a solution (as expected). 2) 2D, no imported mesh: equal num

Re: [deal.II] Reading a Tensor from parameter file

I don't know if it is the optimal way but I would use the following approach 1. Read tensor components as Patterns::List 2. Use get method of ParameterHandler to read all ten

[deal.II] Reading a Tensor from parameter file

Dear deal.II community, I am trying to read a second order tensor from a .prm file using the ParameterHandler functionalities. The tensor (for dim=3) is set in .prm file as set macro def grad = 1.2|0.0|0.0|0.0|1.1|0.0|0.0|0.0|1.4 and is currently read as a string using parameterHandler.decl
