Constrains in Creo simulate

I’m trying to calculate one bracket where hole for shaft. Part is very complicated and there are several forces in different locations of it. So easiest way to constrain part is add constrain to to hole of bracket. It work but it behaves wrong way now. All surfaces of hole are “locked” and it’s quite far away how it should behave when there is shaft in hole. 

One solution would be that turn it other way and add bearing force to hole and cnstrain other surfaces/points but it’s really hard to get right values etc on that case. 

So now would like to hear how that constrain can be done such way that it as close as possible same way as shaft in hole? (contact analyses can’t be used because of our poor license..)
