    Finding transmitted forces in deformed model

    Hi! I'm carrying out a buckling analysis and require to verify the buckling force by hand, to do this I (assume...) I'll need to find the force transmitted to a particular member (my geometry is a car chassis). I've been able to list the forces in a particular direction at every node, if I...

    Finding volume/mass of structure

    Thanks, I got round the problem by listing and summing the length of every line then simply multiplying by cross sectional area and density

    Finding volume/mass of structure

    Is there a way in APDL to find either the volume or mass of a created structure? Its a fairly basic keypoint/line model with a defined cross section, thanks in advance! [glasses]

    "Small equation pivot term" error causes analysis to fail

    That's great, thanks, sorted now! I'm fairly new to ansys and I didn't realise if you placed a keypoint in the middle of a line it didn't become part of the line, silly me! And I just cturned the pivcheck off to highlight where the error was, cheers [glasses]

    "Small equation pivot term" error causes analysis to fail

    An update...adding the command "PIVCHECK,OFF" at the end of the log file allows ANSYS to solve the simulation without the pivot error stopping it and highlights my problem...it seems certain lines aren't actually connected to one another...in certain places ive added in a keypoint using the "add...

    "Small equation pivot term" error causes analysis to fail

    I've created and applied constraints/loads to a fairly simple car chassis in APDL (created using keypoints/lines and defining a hollow rectangular cross section). The analysis works until I add the final 10ish members to the chassis and then the problem wont solve. Instead I receive the "There...
