Hi I am trying to use animation feature in opnet. For that I set the preferences to open animation viewer when the simulation starts. During the animation I am trying to call op_anim_viewer_open which always returns -2. No more subsequent GUI call has any effect. I also do not really know what name should i put into viewer id paramaeter of the call. Especially when animation is only stored in file for later usage. Any advice?
Erasing all temporary files in user home resolved the problem.
