[Gmsh] MSH 2.0 format

[Andrey Zakharov]

Dear GMSH developers.

 

I use GMSH for a long time only for post-processing of transient gas
flows (such parameter as density, velocity components and vector,
pressure, temperature, etc.).

For load this parameters in GMSH I use MSH 2.0 format. I think, that
structure of this format is not optimal, because for every physical
parameter (on every time step) format requires to save node numbers, for
example:

 

Time step 1

 

Pressure (scalar)

 

1 value

2 value

...

N value

 

Density (scalar)

 

1 value

2 value

...

N value

 

 

If parameters will be saved in other format, without duplicate of node
number, for example:

 

   Pressure  Density  

1   value       value       

2  value       value       

...

N  value       value       

 

Then size of output file may be a little smaller.

 

For fine mesh, many visualize parameters and many output time steps the
size of output file is very large.
