Preview After Simulation

Add the script to Simulation Flow (Ctrl/Cmd + F2) > SimulationPost.

Once a simulation has been reached the last simulation frame, RealFlow goes through the simulation, takes screenshots from every frame, and saves them. After this process, a message is being printed in orange to point you to the images' location.

# Get the project's last simulation frame
lastFrame = scene.getMaxFrames()

# If the simulation has reached the last frame get the path where preview images will be stored
if (scene.getCurrentFrame() == lastFrame):
	path = scene.getExportResourcePath(2)
 
	# Create a playback function to go through the cached frames automatically
	for frame in range(scene.getMinFrame(), lastFrame + 1):
		scene.setCurrentFrame(frame)
 
		# Make a screenshot and save the image under the given path from above
		openGLImage = scene.getCurrentViewportImage()
		openGLImage.save(path)

	# Print out a coloured message when the preview is ready
	scene.message("<font color=orange> <font size=3>The images can be found under "+path+"</font>")
