[Gmsh] Python scripts as onelab solvers

2019-12-05 Thread Max Orok

Hello all,

I believe you can only use executable files as Gmsh solvers.
Would there be any interest in using Python scripts as solvers directly?
Perhaps there's a clever workaround used right now.

>From the GUI, I'd like to be able to:

   - add a python solver to the solver list
   - have that solver modify the gui window with onelab parameters, like
   exec solvers do currently

I know about the custom_gui.py demo, but believe it requires users to start
it from the command line.

Maybe this could be a more portable option for distributing solvers or
reduce the barrier to writing one?

Thank you,
Max

Here's how to have a vertical scale 100 pixels from the right edge of the 
window, centered vertically:

test.geo:

***
View "Test" {
  ST(0,0,0, 1,0,0, 0,1,0){1,2,3};
};

PostProcessing.HorizontalScales = 0; // Display value scales horizontally
View[0].AutoPosition = 0; // Position the scale or 2D plot automatically (0: 
manual)
View[0].Height = 200; // Height (in pixels) of the scale or 2D plot
View[0].Width = 20; // Width (in pixels) of the scale or 2D plot
View[0].PositionX = -100; // X position (in pixels) of the scale or 2D plot (< 
0: measure from right edge; >= 1e5: centered)
View[0].PositionY = 1e6; // Y position (in pixels) of the scale or 2D plot (< 
0: measure from bottom edge; >= 1e5: centered)
***

(There is a little bug with vertical alignment in the latest stable release, 
that was just fixed. Use the latest snapshot to test.)

Re: [Gmsh] Change position of value scale

2019-12-05 Thread Marco Tiberga

Dear Max,

Yes, that works!
The scale is vertical now, even though I cannot move it to the right/left of 
the view.. but it does not matter, better than nothing.

Thanks for the help, I scanned through the View options in the manual, I did 
not think of looking at the PostProcessing ones as well.
As a suggestion, I think that explaining what the 
“PostProcessing.HorizontalScales = 0” does in the manual is useful to everyone.

Best,
Marco

I tried with the most recent Gmsh snapshot, but if I go to “View options” -> 
“Axes” -> “2D axes/value scale position” only the option “manual” seems to 
actually be able to change the position. I am using the GUI, FYI.

However, I cannot obtain what I want.
The “Automatic” position is at the bottom-center of the screen and the scale is 
horizontal. If possible, I would like to have a vertical scale, to the left or 
right of the view.

Thanks a lot for your help, in advance.
