Get triangular wave on pspice
You have the op-amp wired incorrectly. Negative feedback is needed and this means swapping pins 2 and 3.

You also have a positive voltage for both pos and neg supply voltages!

A tip for asking questions in future - when you say you can't get triangle waves you do have to normally explain what you actually see - this is important.

Be prepared for a non-ideal triangle wave due to the 100k feedback resistor - it will round the linear ramps of the triangle wave a tad. Maybe try 1Mohm to improve this but watch out for the op-amp's output drifting towards one of the supply rails and possibly clipping the waveform on the output.
