I am writing a model in wich i need to find a point on a line that is at a fixed distance to another point. I constrain the point to vierify the rect equation and to have the fixed distance from the other point. This problem in geometry have two solution, but my model naturally find only one solution. Particularly the solution find is always the solution in direction of "0-point" of the rect. I think that this depends by the resolution algorithm that is programmed to find the solution in one direction. Therefore I need sometimes to find the other solution and I don't know how. There is a way to change the property of algorithm resolution? How I can do it? Anyone can help me? Thanks
Thanks: I installed this package and the problem seems solved.
I installed Openmodelica 1.8.1 on my OS Ubuntu 12.04 32bit following the guide in download section of this site. The installation terminated without problem and all components was installed. But a problem appen when i try to compile any simple system (also default example). The compile crash instantly with a massage similar to the follower:
