    Hi there, I'm using FEBio2 version 2.9.1. Iv created an optimisation file but every time I try and run it I keep getting "Failed initializing the task: optimize". Both the model file and the optimisation .feb files are in the same folder, same working directory. It runs the first model file but fails at the optization file. Any help would be appreciated. Iv tried numerous attempts at other peoples solutions but no luck so far.

    Regards, Lewis

    Hi Lewis,

    I suspect that the first parameter in the optimization file should be:

    Code:
    <param name="fem.material('Tissue').solid.E">470000, 100000, 100000, 1</param>
    It looks like your file is missing the "solid" part.

    Cheers,
