🚀 Explicit vs. Implicit Simulation 🚀

SIMULIA gives you two main ways to run your engineering “what if” scenarios: Explicit and Implicit.

Think of them like two different approaches to solving real-world problems; each with its own strengths.

1. Explicit Simulation

You know those crazy crash test videos where cars get totally wrecked, or when you accidentally drop your phone and everything happens in a split second? That’s where explicit simulations shine.

They’re made for fast, wild, messy situations, basically stuff that’s over in a blink.

How does it work?

Well, it takes things one tiny baby step at a time... suuuper small time jumps, no complicated matrix math... Simple and direct.

Why you’d want explicit:

• It’s a champ at handling big, wild deformations, like bending, smashing, all that dramatic stuff.
• Stays cool even when things get super chaotic, like explosions or impacts.

But there’s a catch:

• It can be suuuper slow for anything that’s not moving fast. Like, don’t use it to watch paint dry.
• Not the best for calm, steady problems; accuracy drops off there.

2. Implicit Simulation

Now, if you’re just checking out how a bridge sags under a heavy truck, or how heat moves through a metal rod, implicit is your pal.

It’s better suited for chill, slow-moving problems.

How does it do its thing?

It’s a bit brainier... Solves everything at once for each time step, doing the heavy math (yep, those big matrices).

Why you’d go implicit

• Way faster if you’re dealing with slow or steady stuff.
• Lets you take big leaps in time; no need for those tiny steps.

Heads up, though

• It can struggle if your problem gets too wild, like, if things are folding or crashing, it might just give up.
• Sometimes, it just can’t find a solution if the chaos level is off the charts.

Which SIMULIA tool does what?

• For the wild stuff (explosions, crashes): #AbaqusExplicit or SIMULIA #CST
• For the steady stuff (structural, fatigue analysis): #AbaqusStandard or SIMULIA #FeSafe.

So, which should you use... in a nutshell?

• Explosions, crashes, fast-moving chaos? Go explicit.
• Slow, steady, or static situations? Implicit is your friend.
