Hi,

 

The model you selected was made by Motorola and unfortunately, when this model was imported into Multisim, the comments to show what this model was designed for was removed.  Some models will not work with single rail.  I was able to find the library where this model came from and base on the comments, this op-amp model was designed for the following:

 

- Positive and Negative Slew Rate
- Quiescent Power Dissipation
- Maximum Positive and Negative
- Output Voltage Swing
- Input Bias Current
- Open Loop Voltage Gain
- Unity Gain Frequency
- Common Mode Rejection Ratio
(CMRR)
- Output Impedence (ac and dc)
- Output Short Circuit Current Limit

 

You can find the original model from here:

The opemp have several models, try the one from TI
