[Gmsh] combine two different msh-file in one window

[?????? ???????]

Hi Christophe

 

Thanks, It works but not all cases.

 

My results are stored along with the mesh and I do File->Open for each file.

It work fine but only for compared time steps of results:

 



 

If time step of one part are greater than other part (18/18 and 14/18
respectively), output picture makes wrong:



 

Area with greater time steps makes invisible L

 

End steps of calculations are correspond of stationary mode and I want to
see this values in one picture.

Hi Andrey,

 

If your results are obtained on the same mesh, just "File->Open" the 

mesh, then "File->Merge" the two post-processing datasets. (Or, if you 

saved the datasets along the mesh in a single .msh file, just "File->Open").

 

If your results are obtained on two separate meshes, just "File->Open" 

the first mesh, "File->Merge" the first dataset; then "File->Open" the 

second mesh, followed by "File->Merge" with the second dataset.

(If the results are stored along with the mesh, just "File->Open" each one.)

 

File->Open creates a new model; File->Merge merges data into the current 

model.

 

By default, Gmsh only shows the current model. To show more use e.g. 

Tools->Visibility->Tree Browser.
