I am working on a design project as a student in a University. We're designing the frame for a small formula FSAE car. I modeled the frame as a simple set of datum curves and points and analyzed them as beams. I was successful checking the stiffness in pro-M by applying a moment to the front and constraining the rear. My next step is to check the frame with the engine installed in place of some of the members. The motor is modeled as a part, so I opened a new assembly with the frame and motor.
My questions are these: What is the best way to model the connections between the motor, which is a 3-D feature, and the frame, which is a set of datum curves? I ran an analyses and it crashed. I assume this is because the motor and frame are only connected by datum planes in the assembly. I am hoping pro-M can analyze connections between the two without remodeling the frame as a 3-D model, or trying to replace the motor with a series of curves.
Thanks for any suggestions, Mike
