I am designing a circuit in OrCAD 16.5. I have added the libraries in the "place part" section and have used the LM837 and LT1115 Op Amps. When I create my netlist, I am getting the warning "No PSpiceTemplate for U5B, ignoring" and the parts do not appear in the netlist. It appears that I do not have the libraries for these files, but I dont know how to add them (or where to get them from). I assumed they were in OrCAD as I was able to place the part. Can someone help me out with this problem?

In Orcad Capture the jumper symbols are contained in the "CONNECTOR" library.
If this library has not yet been added to your project, this is how you find it:
- Open the "Place Part" sidebar.
- Open the "Search for Part" section at the bottom.
- Search for "JUMPER*".
- Double click any of the elements found to add the "CONNECTOR" library to your project.
The answer below is how to properly import a PSpice model (usually generated in a third-party software) into Orcad Capture and PSpice so that both the schematic editor and the simulator work without errors.
Summary
Firstly, the model must be imported into Orcad Capture (so that a new component and a new library .olb is created. Secondly, the model must be properly "fed" to PSpice.
Step 1. Creation of Orcad's component library (.olb file)
- Open Orcad Capture -> File -> Import -> PSpice -> OK
Notes:
a) Field Open: path to the PSpice model
b) Field Save as: path to an Orcad library to be created with a new component. Extension must be .opj
c) Field Schematic Configuration File: leave it as suggested
Step 2. Setting up PSpice simulator
- Copy and paste your model file (e.g. Model.mod).
- Rename the file from Model.mod to Model.lib. This is done, because PSpice works only with .lib extension.
- Open Orcad Capture, PSpice -> New Simulation Profile -> Enter any name for the profile (e.g. tran1) -> In an opened window go to "Configuration files" tab -> Library category
- Enter the path to Model.lib in the Filename field -> Press Add to Design button
- Make sure that the file {Orcad installation directory}\tools\pspice\library\nom.lib is also added to the Configured Files as a Global
- Make sure that in the Library Path there is a correct path to the PSpice main library (see the picture above as an example of a proper path).
Final comments
a) Wrt the error you mentioned "ERROR(ORPSIM-15108): Subcircuit LM741/NS used by X_U5 is undefined", this is caused by improper setting of PSpice simulation profile (either improper path to the Model.lib or main Library Path).
b) Overall, the trick is that import of a PSpice model is done twice: once in Orcad Capture and once in PSpice (would have been better if done automatically by the program).
c) Of course, to add the component in Capture, one needs to add the library (Model.olb) in a Place Part subwindow.
d) Not sure, but likely names of the files Model.lib and Model.olb must be the same, so that PSpice knows what Spice model to use.
Best Answer
you can get PSPICE model from manufacturer company, search on google for example "LM239 PSPICE Model" this will lead you to texas instrument site datasheet page. scroll down and you will see they have provided with PSPICE model.
I've found a guide in the TI's website.
