In this video, learn about the possible errors found in an analysis, and develop an ability to debug the model.
- [Instructor] The Load Case Manager enables us to run and review results from many load cases simultaneously. It's an alternative to setting up individual studies as we did in the previous video. So this video builds on the groundwork set up previously using Load Case Manager. Now I have two study tabs available here. We've just been working with compression case. We can click back to con_rod static case, I can unsuppress the compression load and I have all three loading objects available.
And I can work with these now simultaneously in one single analysis. And that's the key thing associated with Load Case Manager. Now to open up Load Case Manager, we have it here, and I can Save you, and Edit the definition. You may find that the Load Case Manager is set up already, so the spreadsheet is populated. Or you may have to start again from scratch, so we're going to again run through from scratch here. We want to set up first off the Primary Load Case, which we're going to be calling the tension case.
So the compression load object is already suppressed. The tension applied load at the bearing end is there, it's active. We want to invoke the acceleration load as well. So we click on that. Now we have our acceleration load. So the tension load case again made up of two load objects, the tension, applied force and also the acceleration which will create the body force. Now we click here for the next load case, which I'm going to call compression case.
Again I'm now going to unsuppress the compression load, suppress the tension load, and the acceleration is already suppressed. So I just have one loading object present here. Both of them have a check in the box against the constraint, because both are going to be using the big end constraint. We're not going to set up any load case combinations here. We downloaded that before but it's not appropriate in our case. These are the only two load cases, we're going to be working with.
We do want to track the results. So we click here to add a new sensor. We can Add Sensor. I'm going to look at von Mises Stresses. Again make sure we're in PSI. And then we check okay. That's our first stress quantity recovered here. I'm also going to add a second sensor, so Add the Sensor. Again, I'm going to choose the Stress Quantity, it's going to be the X-directional Stress.
Let's choose that there. Make sure the units are in PSI. We check okay. So here are the two result quantities which are going to be spawned in that particular case. Let's just add a third which will be our displacement. So let's add this in. Add Sensor, on the Simulation Data I want, it's going to be Displacement, I want to look at again, Resultant Displacement.
Check the values are in inches. And check Okay. Now we're going to check the Run button and what that's going to do is to solve a single analysis of that single analysis is going to be split or it's going to spawn two separate load cases. So the power of this again is one single analysis, with potentially many load cases. So it's efficient and it's a cheap way of working.
So Run this, and we see an animation indicating the two load cases. Solving the tension case. Now it's going to be solving the compression case. And that's it, that's job done. And what we're looking at is the first result. We can see we've got a new set of Results down here. These were the Results we had earlier. And unfortunately they can't be accessed by the Load Case View. So, it's these Load Case Results which are now specific to individual Load Cases that we'll choose here.
So, we're focusing on these parts of the Analysis Feature Tree. And we're controlling them through the Load Case View. Specifically here, through the Results View. So at the moment I've got Tension Case clicked. And if we look up in the Graphics Window here, we can see we've got Static Analysis, Tension Case. So this is the results of the tension case, are 30 some thousand, the same as we saw before. Now we get some useful summaries coming in here. We've got the maximum value of von Mises Stress, maximum value of Normal Stress, maximum value of Resultant Displacement.
And we can compare these against different load cases. So again, if you imagine if you had 20, 30, 100 load cases, you could very quickly see or even rank which were the important load cases in those particular quantities. So at the moment, Tension Load Case is active, if I click in here, now the Compression Load Case is active. You can see the title has changed in here. We can see the action clearly, that squeezing the con_rod, whereas before we were stretching the con_rod the other way.
So the ability to flip between load cases like this, without having to check and go to different analyses, or use the comparative tables we had before, is very powerful. Again, it's great functionality in SolidWorks, I hope this is again going to be developed out further over the coming releases. So if I want to create a new load case type, I could come back to Load Case View and then I could just add in another Sensor and I could choose for example, 1st Principal Stress, make sure it's in the right units of PSI, click Okay.
So we've created the new stress quantity on the fly here. Maximum Principal Stress. If I go back to the Results View tab. I reselect the Tension Case, notice here we've got Stress3, which is the 1st Principal Stress, if I double click on that, this is the quantity that's now being shown. So Stress3 has been added to the column, it's another quantity that I can compare against. So I can flip between again, Tension Case and Compression Case for those.
So I've got a lot of control on the fly down in here. And what's been added in 2018 is the ability to do a Probe. So again, I can come to for, example, On Selected Entities. Choose the split line here. Update. And create my Plot on the fly, or stresses in that particular region.
So really most of the limitations have now been overcome in 2018, and it's a very powerful way of working. Most of the capabilities which are available within independent runs are now available within the combined runs using the Load Case Option. So now, we'll Exit out of the Probe Result. Now we can close down the Results View within Load Case Manager. I can Save the Model off now.
As baseline_14. So in conclusion, the Load Case Manager is a very efficient way of looking at Standard Plot States across multiple Load Cases. We can also be using the Data Probe as well. And the key thing is, it means that we only need to run a single analysis study, and then we can get to our individual load cases very quickly. So we can adapt our load cases, we can combine them, on the fly and we can look at results, pretty well in any way that we want.
So they're huge advantages in terms of the cost of running because we're only running one analysis. And then just the sheer flexibility of being able to look at multiple load cases, just within one view.
