(OP)
Hello Im having a big problem, im trying to simulate an hidraulic arm in ansys. the model was made in inventor and exportated as a step file .stp

there are no problems meshing the model but when i try to star the solution it shows the following errors.

"Warning: Solver pivot warnings have been encountered during the solution. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully."

And "One or more contact regions may not be in initial contact."

So i dont what the solution could be. it would be very important for me if you could help.

thanks
