Hi,
is there a way to view the initial state (zreo-th frame) in a animation? I always see the state _after_ the first timestep in ElmerPost, but I would also like to sse the state _before_ the first timestep.
Thank you,
Matthias

Re: View zero-th frame in transient simulations
Hi
Well, maybe not for the standard "Post file" option but if you use ResultOutputSolver you can set for it

Code: Select all
Exec Solver = before timestep
Re: View zero-th frame in transient simulations
Hi Peter,
if I use ResultOutputSolver as you suggested, the first view is much nearer to the initial state, but still not what I expect.
I have two adjacent bodies with different initial temperatures, one of them kept constant over time, and I would expect a jump in temperature at the interface before the first timestep. But there is already a slight heat diffusion into the second body.
Do you have an explanation for that?
Thank you,
Matthias

Re: View zero-th frame in transient simulations
Hi Matthias,
The color within elements is based on the interpolated values from the nodal points. If the two bodies
share nodes, there can't be jumps on interfaces. This is btw. also how the nodal basis function based
variables in FEM are constructed.

Re: View zero-th frame in transient simulations
Thank you for this clarification! So what I see (with ResultOutputSolver + gmsh) is really the initial state.
Did I understand correctly that there is no way to see it in ElmerPost?
I did not yet find an elegant way to create animations with gmsh...
Thank you,

Hi,
the ResultOutputSolve can also write elmerpost files, just do

Output Format = String "Elmerpost"
Re: View zero-th frame in transient simulations
Great, it works now!
The only small quirk is that ElmerPost thinks that the first image is _after_ the first timestep, so the time shown has an offset of one timestep.
For the records:
* The filename given to ResultOutputSolver has to be changed so that the output file is not overwritten by the "normal" ElmerPost output file
* ElmerGUI does not know Output Format = ElmerPost. I have added it in resultoutput.xml (see attachment, initial file was contained in Rev. 5270)
Thank you!
