I have created a jupyter notebook where I'm defining a multibody system in order to obtain its kinematics and dynamics.
I use the KanesMethod (from sympy) in order to obtain the equations of motion of the system. However when I try to use trigsimp() on the mass matrix obtained, it seems to get stuck there forever (displaying an 'In[*]' next to that line). The line is: 'mass_matrix = trigsimp(kane.mass_matrix)' Here's a screenshot:https://gyazo.com/8c6ac6cefd87b889a4ed8f9a9c3077d9 (The python process is using ~30% of the processor) The matrix is a 6x6 matrix, but some of the elements have lot's of trignometric functions since there are 3 reference frames with 3D rotations in order to each other. So what's happening? I have no experience with sympy, so I'm a little lost. (I'm sorry if this is a duplicate, but I couldn't find my first publish and I wanted to add more info) -- You received this message because you are subscribed to the Google Groups "sympy" group.
