What the color rendering represents #169

Closed wjsjtu123 closed 3 months ago

wjsjtu123 commented 3 months ago

image image I would like to know what this this color rendering on the ground represents? I have wall boundary conditions turned on, as well as force field.

ProjectPhysX commented 3 months ago

This is the pressure on boundaries as computed in last lbm.calculate_force_on_boundaries() call.

wjsjtu123 commented 3 months ago

So what is the correlation between the amount of pressure and the depth of the colour, for example is the yellow part of the picture more pressure than the blue part?

ProjectPhysX commented 3 months ago

Yes yellow is positive pressure on the walls, blue is negative pressure. I don't yet have a color bar for this but it's similar to density color scale.
