Hello. I am new to this forum.I have a problem at my analysis and i want to ask for some help.My topic at my diploma thesis is "rigid dynamics of a robotic hand".The software i use is ansys 16.2 workbench.I have understand that the hole point is to connect properly my parts together with joints and then put joint loads ect to achieve the move i want(just a simple move from open hand to close).My problem is that i can't move all the fingers together as a unity.I can move tho every finger separately by suppressing the other fingers joints.if all the joints are active my model don't even move.What am i doing wrong?Any help would be useful.Thanks in advance.
