[Libmesh-users] [RB] Print solution vector as ".txt"

[<ss...@pu...>]

Hello, all.

 

To find the maximum solution value, I try to print a solution vector, e.g.,
displacement vector in linear elasticity, as text extension.

However, I was able to find only the solution with the exodus extension. 

 

This exodus extension is useful to visualize with a program like "ParaView,"
but it is complicated to compare results directly.

So I want to print solution with ".txt" as follows: 

 

(node)          (solution)

1                  0.1122

2                  0.5454

.

3224             0.5722

 

If there are multiple solutions such as 2D elasticity (displacements for x
and y directions), I want to print a text file as

 

(node)           (x)                (y)

1                  0.1122           0.5556

2                  0.5454           0.5878

.

3224             0.5722           0.4125

 

Could you please tell me some ways or ideas?

If it is impossible, I want to print the maximum solution value in
"Terminal"  using "std::cout << . << std::endl" at least.

 

I always thank you for your help.
