Four Key Product Features in Creo Simulation Live

Posted by Concurrent Engineering on 09-May-2019 09:37:00

Creo Simulation Live, a real-time, easy-to-use simulation, which is fully integrated into the 3D CAD modeling environment. It allows engineers to iterate design ideas more quickly, generate more options and design with greater confidence. 

Let’s have a look at four of the key product capabilities:

#1 Linear Solver


The linear solver, works on three key areas, looking at structural, thermal and modal - though other types of simulation will be available in the future.

What you’re able to do is rapidly define the simulations. It’s a very simple environment to go and apply your boundary conditions and loads. You don’t have to worry about meshing, as all of the meshing is done automatically.  If you’ve got a b-rep model, the meshing will always work, You don’t need to worry about refining the mesh or improving the mesh in highly detailed areas, as it is all fully automatic.

For those of you who are familiar with Creo Simulate, you will know that when you run simulations in Creo Simulate you can have a quick pass or you can have the full simulation. As we use p type elements in Creo Simulate, we start off with an order three, then raise the order to order four, order five and then we’ll compare the results of say the order 5 with the  order 4, to see if we’re within a convergence value that has been defined. If we have, then we’ll stop the simulation But we don’t have to worry about the convergence in Creo Simulation Live, it’s all taken care of automatically.


#2 Unified Environment

What we mean by this is that Creo Simulation Live is all running within the Creo environment. It’s not a separate app or a standalone product, it runs directly inside Creo. The Simulation Live tab is just another addition to the ribbon and when you click on this, it will present you with the Simulation Live tree.

The really nice thing here is that you can setup multiple simulations. So if you want to do a modal and a thermal, you can set these up under different simulation studies and then simply activate the one that you want to see the results of and then you’ll see the results more or less instantly/


#3 Creo Parametric Models 

Yes, you would Creo Simulation Live to run on a part model, but it also runs in assemblies. If we pull up an assembly and start to do a Creo Live Simulation, what it will do is it will consider all the components to be bonded. We’re not looking at contact analysis here; we’re looking to do really quick analysis, so e consider these to be bonded. Of course, all the individual components will have their own material properties, so if you have a steel component butted up to an aluminium component they will have their own material properties, but where they interface, that interface will be considered bonded.

Another nice thing is that if you’ve already configured some analyses in Creo Simulate, the loads and boundary conditions that you’ve created in that environment will come through directly into the Creo Simulation Live. Though we must caveat this, as there are some things that won’t come through, for example idealisations.

The other really nice thing is you can go and run a Creo Simulation Live session in conjunction with a DEX session. If you want to iterate and come up with a whole bunch of different permeations for your design, you can run this in the context of a Creo DEX session. Then when you’ve decided on the one that you want to go forward with, you can make that the master design, but all the other iterations are stored in the DEX session, including the Simulation Live work on all these iterations.


#4 Interactive Results

When you’ve run the analysis, what do you see? It will display a number of options for you, depending on the type of simulation. In the thermal, for example, you can display temperature and heat flux.

 You can also change the way you render the results. For example, if you run a thermal simulation on a computer, you can change the view from the surface result to the maximum results, to see where the hot spots are inside.

When we’re looking at the results, we also have the analysis legend, which we can adjust to change the limits.
