[Getdp] How to store all nodal values in a file via PostOperation

[Constantin Mokur]

Hi Jens,

thanks a lot for your fast response!
It's a good hint but unfortunately in my case I want to save some calculated values 

(depending on the DOFs) and not the DOFs directly. Therefore I'm looking for a

PostOperation command for this purpose. 


In case there is no such command I could use your valuable hint and write a small
program which is doing the calculations after reading the res file.

But maybe I'm lucky and there is a possibility to do it in the PostOperation.


Kind regards,
Constantin

Hi Constantin,

I'm not an expert in GetDP. But you could use the resolution file
(*.res) for this purpose if you like to.
Whenever you did a SaveSolution in the .pro files, the complete list
of degrees of freedom is written to the end of the resolution file.
So, if you had a nodal based solution this list in the resolution file
is a list of the values at each node. They are sorted like in the msh
file which is mostly from 1 to number of nodes.
The exact file format of the resolution file is in the documentation of getdp.
But probably there is also postprocessing command which I don't know.

Best, Jens.
