    Hydraulic Fluid Compressibility vs. Boiling Point?

    Hi I was interested in understanding what went into the design of hydraulic fluids. I was wondering if there was a trade-off between compressibility and fluid boiling point or breakdown temperature. Is it an inverse direct relationship or something else? I am interested in Glycol based fluids...

    A-Arm Buckling end conditions?

    I want to check the buckling loads because this suspension due to packaging constraints has rather long trailing links (SLA type setup). The suspension is also using a good amount of anti lift as well. I also wanted to be able to reduce the weight of arms by reducing the wall thicknesses from my...

    A-Arm Buckling end conditions?

    Hi I was wondering what the proper Euler Buckling end conditions would be for a individual tubular a-arm link would be. The links are welded to a steel boss with a spherical bearing. The other end of the link has a threaded rod end attached to it. I am thinking that you can assume that the end...

    COSMOS Beam element

    I tried the steering tie rod and now I get a new error, that says "excessive reverse offsets at two ends of beam". Any ideas of what that means? Here are some pictures of what my current setup is:

    COSMOS Beam element

    I tried the direct sparse solver and that did not work, it gave me another error. I have been looking in the .out files but it does not have a line that references what node was giving me an issue or matrix diagonal. It states what the error was, number of nodes, and what options I had, but that...

    COSMOS Beam element

    I am trying to analyze a beam element tube frame vehicle chassis model in COSMOS using the beam element analysis. I am running into issues with Cosmos telling me that "PCG Iterative solver stopped. Status Code 2: Preconditioner_fails_to_factor. May not have sufficient restraints. No results...
