    Complementary study material for FEM

    Hello, as I come to end of my degree I feel like I have consumed so much knowledge some earlier more fundamental topics have inevitably been pushed out of my brain! Whilst I have an appreciation and understanding of general engineering concepts, such as mechanics, calculus, matrix algebra etc...

    Non-constant E total, could it still be correct?

    Hello, I have been reading around online and it seems that this should remain (at least fairly) constant throughout the simulation. I am modelling a bi-stable structure that has an analytical rigid part to move the object into its second stable state, by pushing it in a certain direction...

    Is outsourcing services killing careers?

    Hello, I came across this article which is discussing the average salary of chartered engineers in the UK (£63,000), there seems to be a debate about the accuracy of this figure but the statement chartered engineer spans a rather wide spectrum. What I found interesting however, is that one of...

    Levels of design engineering

    Sorry if this is in the wrong forum. I was unsure where to put it! Just wondering as a mechanical engineer what the different levels of design engineering are. I was recently talking to someone at a large construction and chemicals company who expressed themselves as design engineers, in the...

    Working abroad (and long term travelling)

    Hi everyone, I am currently a student but will be graduating this summer. I hope to save up enough money to be able to go travelling in a couple of years. Whilst I would like to travel for a year or so I am also exploring the option of living abroad and potentially living and travelling long...

    large compay or small consultancy?

    Hello. I am currently deciding between two job offers. I am a graduate however I will be going into work not on a graduate scheme as I am trying to focus on CAE specifically FEA. One offer is for an incredibly large company working in a specific area of FEA. The other is a small consultancy...

    Decisions as an engineering graduate...the trade off between passion and money?

    Hello everyone, I'm posting this topic because I believe this is a debate that affects a lot of young engineers making key decisions at the moment, including myself. There's a diverse mix of engineering students university, everything from hating engineering and wanting to get out as fast as...

    Damping in a dynamic model?

    In a static analysis we are solving: [K]{x}={F} In a dynamic analysis we are solving: [M]{x''}+[C]{x'}+[K]{x}={F} Now by introducing a quasi static problem, the initial acceleration at the beginning of each iteration is 0. so we are left with: [C]{x'}+[K]{x}={F} As I have not specified...

    would you use implicit or explicit for this?

    A whipping motion of a thin sheet. There is a wave that moves through the sheet then I am getting errors with individual elements lighting up and then it aborts. I'm using a quasi static implicit analysis with no damping as its not actually a sheet and it would likely be heavily damped as the...

    Confusion with categorising solvers

    Hello everyone, I have been recently getting stuck into FEA for my work, and I am having some real difficulty classifying or categorizing the breakdown of solvers and what fits in where. I'm hoping that someone can clarify a few things or set me straight. So for all of our problems our...
