Z88 Aurora - free finite element software

Has anyone using Z88 Aurora?

Is it suitable for beginners to learn FEM?

Are there example downloads anywhere?

Is it suitable for boat calculations?

Thanks.

 

I have never used it. I use Cosmos/M

As for is it suitable for beginners?...it all depends upon your knowledge/theory of structures and structural design. You need a good grounding of both to get meaningful results. Since, like any software, anyone can press buttons. But understanding how it works and knowing how to scrutinise it and validate it..is a totally different proposition.

FEA is suitable for just about any application..when used correctly.

 

I am fairly competent in math, having some knowledge of partial differential equations and boundary value problems.

I have been exposed to equations for bending of beams and such, e.g. what partial differential equations govern and some solutions for simple cases (way back when), but I haven't taken engineering mechanics courses, such as strength of materials, etc.

I have some knowledge of numerical methods, such as finite differences, but I am not knowledgeable about finite element methods.

I think finite element methods were not taught in typical courses in numerical analysis back in the mid 70s when I took the courses on numerical analysis. At least they were not taught in my course.

 

Yes, I used to play with it some time ago.

Yeah, why not? I found the manual and tutorial videos quite helpful and they have a nice handbook explaining the basic theories of FEA. In addition it's designed to run on an average PC and it's freeware. They also have a support forum with helpful staff.

If I remember correctly there are example files that come with the installation package.

What are "boat calculations"? If you want to do mechanical/structural calculations, vibration (natural frequencies) and thermal analyses - yes, that's what it's made for.

Fluid dynamics and the like? No.

 

Have you ever tried WelSim? It is an ease-of-use FEA tool for the beginners.
